When one partner, usually the man or dominant in the relationship, is laying on his back... the other partner laying on his chest as a pillow, one arm over, one leg over.
Not to be confused with spooning - the reverse paperclip is when partner one still lays on his back - and partner two is in the aforementioned position only facing outwards.
Founded by the A.S.M (anti spooning movement)
Guy 1: "Did you snuggle after sex?"
Guy 2: "Yeah dude - we paperclipped it up - fuck spooning, I mean i spooned her early in the night BEFORE we fucked..."
Guy 1: "hahaha totally - everyone hates spooning, you just use it to get laid right?!?"
Guy 2: "Exactly... and after I made her say the safety word we drifted off paperclipping"
Guy 1: "awesome - real men don't spoon after sex - spooning is for pussies."
