What the hell is the point of circumcision?

plz explain. Is it like emo cutting? Does it make you look cool? Should I try and circumcize myself? Am I spelling it right? Or am I asking too many questions?

Well, i found out that i wasnt circuimcised. Go me.
I must say, circuimcision is some retarded shit right there. And teachers in sex-ed do a shitty job of explaining it.

"ZOMG a flap over your pee-hole where urine crusts up and you get infect waiiiii!"
