Similar to the snowball, an avalanche is a sex act in which multiple men ejaculate into a person's mouth and that person then kisses another, forcing all of the semen into the receiving person's mouth.
That bukkake party was going great last night, until Rachel got up and avalanched Dave. Dave will never be the same again.

When a man ejaculates on a woman's chest while she's sitting upright. The sperm slides down the chest like snow sliding off a mountain during an avalanche.
