assvalanche

A contingent of people mooning someone via the snowball effect, starting with one person and gradually expanding one at a time until the entire group is mooning at the same time.

The name is derived through its literal meaning: an avalanche-like effect of asses being exposed.

"The whole group mooned me! It started with one person, then another joined in, and then another...it was a total assvalanche!"
