Hearing a song so kick-ass that it makes you wanna beat people up, especially babies.
"Oh did you hear that dragonforce song?. Its so fucking baby punching!
When a guy with a huge wiener fucks a pregnant chick and repeatedly punches the baby with his penis.
"I had a miscarraige hunny, Mike: OMG what happened babe? It was because it was beat to death, doctor said it was most likely caused by baby punching."
