Slore

A slutty and/or whore-ish person at the same time
Origin: A shortened version of two words combined together; Slut and Whore to form Slore, Sl(ut)(Wh)ore
Almost the equivalent of being called a cunt (at least by those who find the word actually offensive)
Generally used as a playful derogatory term but depending on pronunciation and attitude can be used as a full insult

Jesus fucking christ shut the hell up you stupid slore
Kaitlyn- you're such a loveable slore that no one should touch
