SYBAU
An acronym for 'shut your bitch ass up' that resurged massively on TikTok, with kids often lying to adults that it means something wholesome.
Definition
SYBAU stands for 'shut your bitch ass up,' a blunt way of telling someone to stop talking. It's used both seriously in arguments and jokingly as banter between friends, with tone deciding whether it lands as an insult or a bit. Kids frequently tell parents it means something innocent like 'stay young, beautiful, and unique' to hide the real meaning.
History
The acronym dates back to at least 2003 on Urban Dictionary, but it saw a massive resurgence in 2025–2026 through TikTok and Twitter/X, especially in comment sections and reaction videos. A February 2025 TikTok from @onmybehalf deliberately misdefined it as 'so you're beautiful and unique,' which fed into a wider trend of kids inventing fake wholesome meanings to fool adults.
