HML on Snapchat means "Hit my line," which is slang for "call me" or "text me."
Here's a breakdown:
- "Hit" in this context is used as a synonym for "call" or "text."
- "My line" refers to someone's phone number.
Essentially, when someone sends you "HML" on Snapchat, they are asking you to contact them directly via a phone call or text message. It's a quick and informal way to invite further communication off of the Snapchat platform.
