ouffissime

French slang meaning utterly insane, more than unbelievable. It can be used to express great shock, surprise or amazement.

It is a back formation of "fou" meaning crazy, and the suffix "-issime" meaning highly, to the highest degree.

If something is "ouffissime", it is hella crazy and you can't believe it.
"Ça serait ouffissime que tu m'ais ken et que ça soit le truc".

Said by French YouTuber Squeezie on November 15, 2023 in his video "Qui est l'imposteur ?".
