(noun) - To describe a person as both a slut and a cunt, derived from the word "slutcunt"; believed to originate from TAO (Together As One) 2009-2010 when a group of crazy fucked-up kids claimed that they have over used the word slut, so it has lost its meaning to them.
a. To simply insult a person; "You slunt!"
b. A way to express friendship and appreciation of each other; "Hey, nice rave costume, you slunt!"
c. To let your friend(s) know that they're making too much noise in the bedroom; Stripper: "Where's my skirt again?" Howard: "Ey, slunts!"
