Someone who can call their friend a slut, but has a problem with somebody who's not a friend calling them a slut or using the word slut, is by definition the worst kind of hypocrite. Like an asshole who does not know he's an asshole, this kind of hypocrite doesn't ever see who they really are, and is usually apologetic without knowing why they're apologetic or what for. It's better to do something on purpose and be a rude asshole about it than say you're sorry when you're full of shit and don't mean a word of what you say.
