SYFHAU (shut your fun hating ass up) is a modified version of the acronym SYBAU (shut your bitch ass up) used to shut down someone who’s trying to ruin the mood, kill the vibe, or be unnecessarily negative about something fun or harmless. Perfect for when someone starts acting like the fun police

Guy 1: Erm, actually, using a nerd soyjak against me is actually very offensiv-
Guy 2: Bro why do you always have to take things so serious syfhau
