sybau
("S"hut "Y"our "B"itch "A"ss "U"p)
The phrase became popular in Gen Z culture as their new favourite way to shut someone down who is speaking by using this dismissive insult. It first started being used all over TikTok but is now becoming popular on other social media platforms and messaging apps now as well. Because the expression was used so often, people began abbreviating it to the initials, which eventually turned into the slang term SYBAU.
