Dude's term for a woman in whom he has no interest other than sex. Fuckmeat (or fuck meat) need not be trashy and filthy and slutty like a cum dumpster. Being fuck meat has more to do with dude's attitude towards HER than with her or her behavior. She may be a sweetheart that’s really all about him, and not at all a slut, but he's just not that into her, so to him, she’s just fuck meat. But at least she isn’t a cumdumpster.
"It's so sad to watch; Beth is SO into Rafael, but she's just fuckmeat to him."
