A rule used by school fuckboys explaining how you can leave a classroom if the teacher doesn't show up in 15 minutes. The rule is obviously untrue.
Fuckboy: Hey guys, have you heard of the 15 Minute Rule?
Everyone else: No.
Fuckboy: You know, if the teacher doesn't show up in 15 minutes we can leave the classroom.
*INCREDIBLY LOUD SIGHING*
