look up any word, like ratchet:
A sex position similar to a piledriver where the penetrating partner, instead of pushing down, pulls the receiving partner up by the hips while the receiving partner rests his or her shoulders on the floor. The motion resembles the motion of operating a bike pump.
Greg: You and Jillian get it on last night?
Jake: Hell yeah, I rusty bike pumped her.
Greg: Nice.
