creepy classmate

this guy is so fucking weird and sexual and just yells it outloud in class and i snap and tell him to shut up every once in a while but i just need to complain. WHen his friend said he wanted to become a p.e teacher he said "yeah to look at ass, thats why id become a p.e teacher" or something along this lines. even his friend was weirded out. they both thinks its soooo funny though. like what? based off the shit this guy says i wont be suprised to see him on a sex offenders list 10 years in the future. he's the type of guy who thinks anything gay is funny. and hes here joking sbout child porn. im suprised the teacher hasnt told him off yet becouse what the fuck. 

edit: the teacher finally said something, but only after he told his friend (accross the classroom) to "shut his bitch ass up". also im writing this in class but im done with my work and she isnt leacturing so its okay.
