slam-pig noun
A woman who engages in promiscuous sexual intercourse, usually characterized by her finding great pleasure in being fucked roughly or ‘slammed’. The reference to the word ‘pig’ in this term is often mistaken as meaning that the woman is overweight, but it actually refers to the glutinous nature in which she engages in sex and often hints at her eagerness to swallow seminal fluid.
