Intricate front hair flip to the side and a push up of hair from the back, put out the shoulder, and smile.

Friend1: "Hey how are you going to do you're hair tonight?"
Friend2: "I'm going to go yaso tonight!"
I cant wait to see your yaso..

Playful acronym for "You Are So Old". For when someone shows their age, or is just being campy, or old-fashioned. 😅 Often over text. Usually said with fondness.
Oh my gosh, no one says ROFL anymore, YASO. 🤣
Awe, you've got a flip phone, YASO! JK Gen Z is all for it.
Oh YASO... but I do respect a Zaddy. 😉
