If a man has an erection and he's about to go somewhere where the erection would be inappropriate, he will masturbate to get rid of the erection before he leaves.
Tom: Damn, that girl's hot
Mark: Hell yeah she is
Tom: Man she makes me hard, how are you not?
Mark: I waste bated before I left home so my mom wouldn't see my boner.
