Undercover Snowblower
A sexual maneuver which involves a BJ under the covers, then spitting it all over the dudes stomach - then probably rubbing the blanket on it and you end up getting banged in the butt by the same dude, thereby having the "snow" rubbed all over your back as well. Also it probably has something to do with night time.
Last night I got so drunk I ended up giving a guy an undercover snowblower.
