When having sex from behind, in the "doggie" position, you knock a girls arms out from under her and pull them back above her head, smacking her head against the floor and making her into a virtual plow.
(Walking around while in this position is optional)
Last night me and Becky were having sex and I pulled the amish plow! I'll never see HER again!
During sexual intercourse, namely doggy style, the male swipes both arms from underneath the female. Thus causing her face to plow violently against the ground/bed, which in turn, causes a massive rash to appear.
(works well on carpet)
Friend: "Hey Kristine, where did you get that fuckin massive rash on your face?"
Kristine: "Oh, one of the Basketballers was fuckin me from behind on the carpet and he gave me the amish plow..."
Friend: "HAHAHAHA! You dummmmmmmmmmmmmmmb cunt! I told you to quit bein' a groupie slut!"
Kristine: "I know, i know... but it hurt soooo good!"
