Two strongmen competitors injecting steroids into each others asses while sticking their dicks in between each others biceps to oil up for a show. This is all done inside of a 1964 Chevelle while Lil' Jon's "Get Low" and Devo's "Whip It" play simultaneously. This usually results in both being filled with a sensation that they are nodding on Oxycontin with Vick's Vapor rub in their noses with half a broom stick shoved in each others ass.
Hey Jerry, our show's tonight, you up for a quick muscle bumper?

That was one hell of a rave last night, I feel like I've just had a muscle bumper!
