dame blanche
When you cum on a girl's chest and poop on it afterwards.
"I f*cked this crazy chick last night, she even asked me to do a dame blanche on her!"
Dame blanche
Having a wank and pooping while taking a shower at the same time. Then pushing the semen and poop down the drain with your toes.
I had a great Dame blanche this morning, I am ready for the day.
