a method to dampen loud orgamsic screams during sex.
When you place you place the palm of your hand on your girlfriends mouth to keep her loud orgasmic screams down so that no one can hear her in the other dorm rooms!
Dude one: "boring night?" Dude two: "no man got laid!" Dude one: "I didn't hear a thing?" Dude two: "ya nasty loud, I thought nothing could dampen her enthusiasm, I had to use some palm muting to keep it down!" Dude one: "awesome!"
