To get absolutely and positively owned, used, or abused. To be tossed down like a used dish rag after the dishes have been done. Generally used in the contexts of American football, fighting, and relationships.
A term coined by Andrew Dice Clay in the 1980's ("The Day The Laughter Died". I interpreted it as meaning an extremely slutty lady, not necessarily a prostitute, who has much in common with a wet, dirty sink rag. After much use a dishrag stinks, has unidentified biological material stuck to it and can even spread diseases if not properly cleaned.
A Dishrag whore is a dirty little slut that can't walk past a male specimen without dropping to her knees or spreading her legs. Usually these whores have meat flaps that resemble a dripping wet rag, usually as a result of too many dicks goin through her.
The feminine equivalent of teabagging; whereby female genetalia are used to smack someone in the face, giving the sensation of being dabbed with a warm, wet dishrag. Oftentimes leaving a residue.
