A Slampig has pretty much summed up by the many definitions before this one. A slampig is a dirty whore who is good for only one thing...fucking. She is a piece of meat, no matter how big or small, no matter how ugly or hot. Bottom line...You fuck her and get the fuck out (but not before nutting somewhere on her body, preferably face).

A slampig can be identified by two whistles blown into a bottle pre or post ceding the word "Slampig!"
In a bar and two whore-ish dressed girls (possibly know sluts) walk past a group of guys. One guy blows two whistles into is Bud Light bottle and immediately follows with, "Slampigs!" The group of guys laugh hysterically.

a fat drunken whore, muffin tops leaking over her belt, titties falling out of her shirt, who loves to get plowed. the type of girl you who makes you throw up in your mouth when you realize where you stuck your dick the night before.
check out Smoltz and that slam pig - she's dying for some cock and he's clearly shitfaced enough to give it to her.

A girl who is about average looking that likes to have random sexual encounters with many guys when she gets drunk. She loves to hook up, give blowjobs, and essentially get railed. This type of girl is every guy's perfect woman because she won't constantly call you, and won't blow your spot. Directions for using a slam pig: talk to her, smash that ass, and kick her out. She'll love it.

That slam pig will bang anyone.

An unplesent looking girl who gets consistantly railed and takes pleasure in that fact. The more penis' taken, the more satisfied this species becomes. Between a Slam Pigs legs is an excelent place to find a plethora of STD's.
