how do you call it ?

I call it a slam piece.

I call it friends with benefits and I have WAY too many •~•

fuck friend

Well, I see friend with benefits and sex friend as someone who is a good friend and you occasionally have sex with, fuck buddy and booty calls are just someone you fuck a lot

friends with benefits

I call it a mistake

@You see I gave a fuck once.. Now what is life when no one wants to try. Hahaha

cuddy buddy

No such thing as a "sex friend". "Friend with benefits" and "fuck buddy" are different things on the continuum from NSA to committed relationship. "Booty call" is very close to "fuck buddy" but with a slight unilateral negative connotation.
