It is when you 69 somebody and they shit all over your face and upper chest.
Me: Last night, Miranda and i 69 avalanched. It was heaven on earth!
Charlie: Man, I wish me and my girlfriend would let me do that!
Me: Yeah, I find that a good old fashioned 69 avalanche spices up any relationship, its worked for me!
