See snowballing (after ejaculation in someone's mouth, they pass it to another person, or the person who came in the first place). Avalanching is passing said 'snowball' down a line of people...thus, an avalanche.

When after recieving a polar bear(blow job w/ ice cube) from a female, the man skeets in her mouth suprising her and therefore making her swallow the lode or spit it all out onto her tits. thus resembling an avalanche.
after giving your daughter a sick avalanche, i was able to use the ice, jizz, and spit she regurgitated as lube to then give her a killer valley forge like i used to give your wife and sisters. Damn cutty, that bitch is as fucked up as you; after giving your entire family alaskan fire dragons she still wants to fuck without protection.

The act of receiving a blow job at the top of a stair well. When a guy comes to his climax, he ejaculates all over the girls face and then kicks her down the stairs. While falling the guy yells AVALANCHE!
