Cunt Cousins 

Two females who engage in an intimate, scissoring, one night stand. The two may never see each other again, but they will always be cunt cousins.

"Wow I can't believe how drunk I was last night. I hope I don't see my cunt cousin anytime soon!"

Cunt Cousin 

A girl who has slept with the same guy as you have. So you have therefore become cunt cousins because you've both had the same dick in your cunt.

"Jenny fucked Tom too, means me and Jenny are cunt cousins".
