Notice a pattern? There's slang and then there's slang in which you sound like you've been slapped around a couple times with a two by four. I actually don't hear anyone say these words--they're more often than not written on the internet somewhere by female posters. In some ways, it's on par with LOL, ROTFL, and emoticons. And in other ways, it's worse--the kind of worse that makes fingernails on chalkboard sound like Beethoven's Fifth. Unless you're trying to make some sort of rhetorical (or perhaps comedic) point, it makes me think that you're linguistically lazy.
