Mukbang
a type of youtube video in which you watch a floating face eat random shit and it's really funny at first but the more you watch it the more pleasing it is and eventually it is so pleasing you cum all over your pants.
John: "Hey Jimmy, come watch some Real Mouth Mukbang with me! It's hella funny!
Jimmy: "NO! Last time I watched it I filled my entire bathtub with cum!"
