Sticking your hand up a girl's anus, as in fisting, and you grab onto her intestines and pull them out. People who do this are called Dutch Munklefuckers.
"Dude I stuck my hand in my girlfriend's ass and pulled her innards out! It was hot!"
"DUDE! You're such a Dutch Munklefucker!"
"DUDE! You're such a Dutch Munklefucker!"
