1. An epithet reserved for a real around-getting cunt-diggity-wad when neither cunt nor slut will suffice. 2. A more obscure yet increasing usage has found "slunt" to refer to a particularly sloppy vag, though it is not unreasonable to combine this usage with the more common application, semenfully. 3. To engage in the act of being a slunt.
1. This word could be assumed that it is a combination of slut and cunt. It is merely just for vernacular. It is assumed that people will think that because of the offensive sounding nature of the word. It is a derogatory word for women that has as simple a meaning as the word FUCK. It can mean anything you want, but has no official recognition as a word.
