It just irritates the fuck out of me when people write an obvious swear word but either omit letters or "censor" them with eg. *, like that somehow makes it not swearing even though EVERYBODY KNOWS WHAT THAT FUCKING WORD IS.
Either don't swear if you think it's so bad, or just write the naughty words out instead of pretending "f*ck" isn't a bad evil naughty word because you hid one letter like a fucking mentally deficient child.
