McRib

(verb) To be tempted to engage in a fast, messy, momentarily gratifying encounter with a sporadic visitor who is in town for a short time. To cause someone to consider a sexual opportunity primarily because of its limited availability.

Dude, why'd you hook up with that one girl who transferred?

I dunno. She said she was only back for the weekend, and that she didn't know if she'd ever be here again after that. I couldn't resist.

Man, you got McRibbed.
