Someone who leaves your innards feeling abused. A guy who is often portrayed as a douchebag but rarely is one. A hot guy who is great in bed.
Guy 1: I was talking to Annie yesterday, she said she hadn't been able to walk, and was feel like crap

Guy 2: lol, apparently im a Thunder Pounder and i didn't even know it haha
