I saw in a recent thread mention of occasional photographers paying for models to pose in particular ways, then later referring to them as sluts for having done so. It set me to thinking that such hypocritical slut-shamers should have their own name.
I suggest, for for your consideration:
A sludge / a sludger: a slut-shamer. Ex: That sludger's just left another fart in the air.
The act of sludging: sludgefarting.
A sludger: a man who pays for a model to behave a certain way, then calls her a slut for doing so. A sexual hypocrite. Ex: He's layed another sludge egg.
A sludgeoprat. He's just a sludgemaaf, innit? (A sludgemouth.) Herr Sludgefater.
