sometimes i ask my friend about different names in english translation and chinese. i have learned now that on chinese this gesture translates as "hey hey"
i think it's a better name for it. it doesnt look like a real "dab", and dab is already a dead meme that many people used to hate. the addition of this gesture feels like a boomer trying to please younger audience, yet he didnt know that time has moved and no one cares about dab right now
