Fuckquaintance 

A person you causally have sex with, but don't like or know enough to call them fuckbuddy or fuckfriend.

Facequaintance 

Someone who you have 'friended' on Facebook but don't really know or keep in touch with. You generally don't know anyone who ever comments on their Wall and wouldn't know them even if they walked right up to you and slapped you.

"Yea, I'm friends with her but we've only met, like, once. She's just a Facequaintance."
