booking up 

When two people are all over each other's facebook walls, constantly commenting on statuses, pictures, posts, etc. Instead of hooking up, they're booking up.

Friend 1: "Man what's going on with Ben and Kayla? They comment on everything the other one does on facebook."
Friend 2: "Guy, they're totally booking up."
