When a male or female lays done on their back and their partner crouches with their ass in front of the other persons mouth. The person laying down licks their partners asshole untill they eventually start shitting and it gets all over the other persons body. Thus the "Chocolate" starts "Rushing" forming a "Mountain" on the perosn laying down.
dude she totally gave me a chocolate mountain rush last night bro, shit got EVERYWHERE!
