A person who has relations with a so called "slut"
That slut banger nailed that whore last night.
A man (usually) who has little self respect or self esteem and in desperation fucks sluts just to get some. This man can also be an all time loser and therefore cannot get a decent woman and has to fall back on sluts and hookers just to give his hand a rest.
John "Oh wow a slut, I will get laid they never turn anyone down!"
Slut-"Oh fuck another god damn slut banger loser, why do I feel sorry for these guys?"
