sfiymp 

sfiymp is a word created for the sole purpose of teasing your friends. This word is like the word from spider man far from home that MJ discovers while in Venice boh that can vary in definition.

The word sfiymp is a good practical joke to have between friends to annoy someone when they can't find the definition on the internet. It works well because there are millions of acronyms that you could create for this. Go crazy!

"did you see her haircut, sfiymp!"

"what does sfiymp mean???"

"what do you mean?!?! You should search it up."
