The act of beating someone so badly at something that instead of “beating the shit” out of them, it comes out in such large volume that it is virtually pumped out of them, hence "shitpumping". Also applies to drinking: If you think you were out of it when you got "shitfaced", wait till you drink so many coors lights that your friends deem you "shitpumped".
“That all chick team seriously sucked at dodgeball, I could have shitpumped them on my own” OR “JS sure went off the chain last night… guy drank 14 Tecate’s, he was shitpumped.”
