Cunt Rag (kúnt rag)
Derrived from the derrogitory term for a disliked woman, and the slang word for a woman's menstrual perid, Cunt Rag is loosely used as a replacement for "Tampon". It is implied that the tampon has been used, and the said tampon is soaked with blood, meaning that whomever is called a Cunt Rag is the lowest of the low.
