The endowed ability to penetrate/pump a vagina so hard and deep the unlucky woman's guts get beat with a penis. Indicators of completing this process are recognized by, but not limited to; loud painfull screams, "stop it's", and vaginal bleeding. Statisticly, sluts are at the highest risk of beaten guts due to their ability to take punishment.
I was beating guts so hard last night, I poked her stomach.
