When you take a girl, and fuck her in a doggystyle type manner with her legs wrapped around your waist, holding her hands as handles, and her face in the ground as a plow as you're plowing the shit out of her; thus, the Alaskan snowplow. Works best on carpet and/or snow.
Dude my bitch made me eat her carpet last night, so I made her eat my carpet with the Alaskan snowplow.
an act of sweet, sweet love making. The male reaches around the female and jerks her arms out from underneath her while doin her doggy-style. This causes the female partner to smash her face into the ground. After contact between the ground and her face has been made, the male proceeds to continue thrusting. Thus causing her face to slide along the carpet like a snowplow, and giving that bitch one monstous case of rug-burn.
