A sexual act in which a couple gorges on spicy Mexican foot in the evening in preparation for sex later that night. Later in the night, the couple engage in sex doggy style and the woman develops uncontrollable, blow out diarrhea. At this point, the man grabs her arms, pulls them back behind her, and revs her like a dirt while she sprays feces all over the both of them (much like revving a dirt bike stuck in the mud)!
The Dirt Bike Strictly for pros. This is when you have the girl on all fours, and you grab her wrists and pull her arms out while she is spraying diarrhea out (thus giving the image of you riding a dirt bike).
