Chicago Snowblower

A sexual act where, at the conclusion of sex, a male ejaculates violently and excessively somewhere in the room, recreating a snowblower blowing snow. The semen is left in place for several weeks until it starts to smell and stinks up the entire room, much like how the entire city of Chicago smells awful.

"I gave Becky the good ol' Chicago Snowblower a few weeks ago and man, does my bedroom smell like shit!"
