When a girl is giving you head at the top of the stairs and you blow your load in her face and push her down the stairs.

Snowy white avalanche

The act of ejaculating on a girls face then pushing her down the stairs.

Todd ejaculated on his girlfriend, pushed her down the stairs, and screamed "SNOWY WHITE AVALANCHE!"
