Friends with Fits 

Similar to the more common "friends with benefits" expression, but the participants engage only in "clothes-on" acts, e.g. light making out, cuddling, and extreme cuddling.

"Damn, man! You got Janine to agree to be friends with benefits?"

"Nah, dude. We're just friends with fits."
