1. DL = Down Low (the most searched meaning)
In modern texting and social media, “DL” is short for Down Low, meaning something is being kept private, quiet, or secret. If someone tells you to “keep it on the DL,” they’re asking you not to tell anyone.
Examples:
- “I got the job offer, but keep it on the DL until I give notice.”
- “We’re seeing each other, but let’s stay DL for now.”
- “The surprise party is DL — don’t say anything to her.”
Where the phrase came from
“Down low” existed in everyday English long before texting, simply meaning secrecy or discretion. The specific abbreviation DL became widely known through African American Vernacular English (AAVE) in the 1990s, where it described men — often publicly identifying as heterosexual — who had secret sexual relationships with other men while keeping that part of their lives hidden from partners, family, and colleagues. This usage was documented by researchers and journalists and entered mainstream awareness after J.L. King discussed his own experience on Oprah in 2004 and published On the Down Low. Author Keith Boykin’s Beyond the Down Low later offered a fuller picture of what life on the DL actually involves, and why acceptance — not secrecy — is the healthier long-term outcome for the people living it.
Because of that history, “DL” carries real weight in LGBTQ+ contexts specifically: it can describe a man who is closeted, questioning, or not ready to publicly identify as gay or bisexual. It’s worth using this specific sense of the term thoughtfully rather than as a punchline — for the people it actually describes, it’s tied to real questions about safety, family, and identity, not just texting shorthand.
Over time, the everyday, non-sexual use of “DL” broadened. Today, most people using “on the DL” in a text just mean general privacy — a surprise, a job offer, a location, or an opinion they don’t want repeated. It’s rarely meant to sound shady or dishonest; it’s closer to “just between us.”
DL vs. similar terms
| Term | Nuance |
| DL (Down Low) | Casual, informal request for discretion |
| Confidential | Formal, often workplace or legal |
| Low-key | Similar vibe, more about attitude than secrecy |
| Hush-hush | Playful, often used for gossip or surprises |
| DM | Totally different — “Direct Message,” not secrecy at all |
2. DL = Download
In gaming, tech, and social media captions, “DL” is shorthand for download — pulling a file, app, or piece of media from the internet onto your device.
Examples:
- “The DL for the new update is 20GB.”
- “Link’s in bio, DL it now.”
- “Is the DL free or paid?”
Related shorthand you’ll see nearby: DLC (downloadable content), DLD (downloadable), and DLO (download link). This is the meaning most likely to appear in gaming Discords, torrent/file-sharing communities, and music or mixtape culture, where “new DL” simply announces new content is available to grab.
3. DL = Driver’s License
In everyday conversation, official forms, and legal contexts, DL stands for Driver’s License.
Examples:
- “Bring your DL and proof of insurance.”
- “The defendant’s DL was suspended for six months.”
- “You’ll need your DL number to register the car.”
This is the meaning you’ll see most in DMV paperwork, insurance documents, rental car counters, traffic court records, and ID verification forms — a completely different register from the slang use above, which is exactly why context matters so much with this abbreviation.
4. DL = Deciliter (dL)
In medical and scientific writing, lowercase-style dL is a unit of volume equal to one-tenth of a liter (100 mL). It’s the standard unit used to report blood glucose, cholesterol, and other lab values in the United States.
Example: “Fasting glucose: 95 mg/dL” means 95 milligrams of glucose per deciliter of blood.
5. DL = Distribution List
In corporate and IT environments, a DL is a pre-built group of email addresses that lets you message everyone at once without adding each person individually.
Example: “Add the new hire to the marketing DL so they get team updates.”
6. Other Professional & Technical Meanings
DL shows up across dozens of specialized fields. Here are the ones people actually search for:
- Data Link — a networking term for the connection layer between two directly connected nodes.
- Deep Learning — a subset of machine learning using neural networks; common in AI/tech writing and job listings.
- Dead Load — in structural and civil engineering, the permanent, static weight of a building’s own materials (as opposed to “live load,” which is variable).
- Deadlift — in fitness and CrossFit logs, one of the core barbell lifts.
- Defensive Line — in American football, the front line of defensive players (tackles and ends).
- Distance Learning — coursework completed remotely rather than in person.
- Direct Laryngoscopy — a medical procedure used to examine the throat and vocal cords.
- Don’t Lie — occasionally used in casual texting as a call-out, though this usage is far less common than the others above.
How to Tell Which Meaning Is Right (Context Checklist)
- Check the platform. Gaming Discord or a torrent group → Download. A DMV form → Driver’s License. A lab report → Deciliter.
- Check who’s talking. A friend texting about weekend plans → Down Low. A coworker cc’ing a group → Distribution List.
- Check the surrounding words. “On the DL,” “keep it DL,” “stay DL” almost always signal secrecy. “DL the app,” “here’s the DL link” almost always signal download.
- When genuinely unclear, just ask. “Do you mean download or keep it quiet?” resolves it instantly and doesn’t read as awkward.
People Also Ask
Most often, “Down Low” — keeping something private between you and the person you’re talking to.
Usually that the relationship is being kept private or undisclosed for now — not necessarily dishonest, often just discretion until the couple is ready to go public.
It describes someone — historically often a Black man — who is not publicly out and keeps same-sex relationships or attraction private. It’s tied to a specific cultural and historical context, not just generic secrecy.
Not inherently. In casual texting, it’s a neutral, common way to ask for discretion. In its specific LGBTQ+ historical sense, it’s descriptive rather than derogatory, though it’s worth using with the same care you’d use discussing anyone’s private life or identity.
Deciliter — a real, standard unit of measurement (100 mL), not a typo or error on your lab report.
No. DM is “Direct Message” (a private chat feature). DL is either “Down Low” (secrecy) or “Download,” depending on context — unrelated to messaging features.
Driver’s License — almost without exception.
Usually Deep Learning, in AI/ML-related job listings and technical writing.
Same core meaning, different register. “DL” is casual and best for texts between friends; “confidential” is the appropriate word for work emails, contracts, or official communication.
Conclusion
DL has many meanings, but the correct one always depends on the context. In everyday texting, it usually means Down Low (keeping something private), while in technology it commonly means Download, and in official documents it almost always refers to a Driver’s License. In specialized fields, it can also stand for Deciliter, Deep Learning, Distribution List, and several other terms. When you’re unsure, look at the surrounding words and where the abbreviation appears—the context will usually make the intended meaning clear.
