Back Door French Kiss

A Back Door French Kiss is when one person places their own anus against someone else's anus and then proceeds to defecate into the other's anus.

Me and my girl did some back door french kissing last night!

French Backdoors

Simlar to the French Kiss. (A kiss with a tongue), but instead of oral, you use anal activity.

Dude have a mint, your breath smells...

I Gave your mom French Backdoors last night, thats why my breath is not fresh anymore.
