Shish

A word great for people that can't spell. Yeah, all your friends will probably bully you, but who cares because if you use this word you probably have no friends anyway. Yeah, it means sheesh but spelled wrong.
You must say it like Sh-ish.
I mean or it's just a shish kabab.

Cool dude: Oi you, wanna come to a party at my place

Loser: Shish, a cool guy is talking to me

Cool dude: Yeah, I was talking to the guy behind you. Ugh
