The act of giving oneself an Alaskan Whaler(whiping semen on one's upper lip dirty sanchez style), then proceeding to thrust one's face towards the recipient's vaginal region(muff diving)and plowing through the vaginal lips.
Before Roberta and I got to bumping uglies, I gave her a major Wisconsin Snowplow to show her I meant business.

When your girlfreind is on all fours and your doin her from behind, in the middle of it you swipe her arms out from under her so they're straight out and fuck her till she plows the covers off the bed. Thats the wisconsin snow plow!
