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.

A highly unattractive or repulsive female who you would only have sex with if highly intoxicated or high off a particular drug.
Tim was so drunk last night he they had sex with the fattest slam-pig at the party.
Tom drank so many cosmopolitans that he began sucking face with the 400 pound slam-pig at the bar.
