A person who drinks Red Passion Alize and then proceeds to hook-up with whatever has at least two legs and two breasts. On second thought, anything that moves.
"Look at that long haired grease ball being a slopster with that girl, wait a minute, is that a man/monster???"

A Slopster is a disgusting creature or group of creatures usually found at bars trying to look hot. They could be overweight, hairy, covered in acne, or just plain ugly.
Damn I was so drunk last night I brought home a slopster.
