Many of TikTok’s most commonly used abbreviations

like the afforementioned /SRS and /s, are referred to as “tone tags,”

or quick additions that can help indicate an upload’s intended inflection or intention

but not all shorthand falls into the “tone tags” umbrella

Some terms, like BBL, are actually just shorthand for a longer set of words.

Back in the day, a quick message with “BBL” almost certainly indicated that a person would “be back later.”

This, along with “AFK,” or “away from keyboard,” is still heavily used in some corners of the internet

like on Twitch or Reddit ⏤ but on TikTok the abbreviation has taken on a meaning of its own

On the popular video-sharing platform, if you stumble upon a post about BBL

it is far more likely taking about a Brazilian butt lift.
