When you are steamrolling and beforehand you break your penis into the form of a hook so you can penetrate someone anally.
"Man, me and champ were steamrolling yesterday and i slipped him the ol' captain hook. Score one for the home team!"

When you(a male) and a preferably another male(for the muscle) either clothed or naked, roll on the ground with each other, each trying to roll over the other. When naked some call it sex, but i like it.
"Wow, Corey, you steamrolled like twelve guys yesterday, plus those two elementary school kids. Thats like a record or something, you should get a trophy for that!"
