v. When one is engaged in missionary intercourse, the partner reaches around and puts a dildo in your ass while you simultanously rail her (or him I guess, don't know how it would work but I'm sure someone has found a way).

Hunter: Last night was crazy bro, I gave Alicia a cleveland steamer and she gave me the best ass pimpin of my young life!
