My 83 year old friend put me onto this. it‘s so fun to say. you can use it to gas up a friend for something cool or you use it when people are being annoying and pretentious.
i’ve yet to see any modern phrases hit as hard as when my boy gave me some knucks and said “stay swaggy”
some others i like are:
yolo
like a boss
get rekd
u mad bro?
what the frick
i mustache you a question
