Noun: A woman that enjoys sexual intercourse with many partners. She is usually very unattractive and persistent with her targets. She often goes for several members of the same team. This could include a college football, basketball, or especially hockey team. She will have no self respect, nor will she recieve any in return. And although most do not like to admit when they have become the victim of such a swamp creature, it usually inspires a good locker room story.
"I went into Rick's room this morning to wake him up for the game, and what do I see, but the largest whale of a slag known to man."
"So Patty was makin' out with this chick at the bar, and then on the walk home Joe finger blasted her on the street. What a fucking slag."
"If you wanna talk slagtastic, lets talk about Katelyn Brown. I've never seen a girl begging for an eiffel tower quite so badly."
