P.I.S.S.H.E.A.D.

Another word for chain smoker, especially if they smoke bidis. Usually they hide their cigarettes, joints, bidis, or whatever in their backpacks, then smoke them in the school bathroom. They also attempt to fuck at school, but none of the girls like them.

There are too many P.I.S.S.H.E.A.D.s at my school.

He asked me how to get to the library. I forgot where it was. I had just left the library. Such S.I.S.A

She just changed her profile picture to be the cover of a book authored by a guys named Funk and Seamon... epic S.I.S.A.

Girl: "Hey, wanna come over later to, ummm, study"
Guy" "Do you mean sex?"
Girl: "Oh, God no, sorry, I momentarily forgot the word "study" - I didn't mean to suggest, no, i mean, not that I wouldn't be into it. Oh, God. Um, so, does 11 work?"
Guy: "S.I.S.A... i get it. I'll bring my Funk & Seamon study guide."
