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.
My whole apartment reeked when that dishrag whore took her panties down.
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.
" I had to double park my cock on the dishrag whores' ass for an hour and wait my turn"
