teen 1: hey i think you have some dirt on your upper lip.
teen 2: oh no, thats my mustache.
teen 1: .....HAHAHAHAHAHAHAHAHA, but seriously nice mexican mustache.
The act of jizzing under a girls nose and then ripping off your own pubic hair and placing it on top of the jizz so it will stick.
Hey Kathy, make me a sandwich or I will give you a mexican mustache.
