I know right. I mean I use 'Fuck' when I'm either excited or mad. But use it in every sentence can be a little rude and just plain vulgar. I mean you're talking to a cop and you're fucking talking about a fucking dude that didn't do the fucking stop sign... hmm, first of all, it sounds rude and second, it loses its impact. I mean the cop is going to look at you like... "here's some soap go wash your mouth" I use them in my WIP in distinctive situations and even then I substitute it with a crap or shit.
