My family been known to use the word lots of times, too. People use it por atuação cool or por frustration and anger. There are many people who don't swear at all.
I don't know. I try my best not to say it directed towards someone or something, but sometimes it'll just escape my mouth on impulse. Like if I stub my toe, or mess up on a drawing, or have had bad luck and I'm just there like, "Are you fucking kidding me?!" Or if I'm really passionate about something, like bullying or gay rights, that's the only time I tend to use negative words like "motherfucker" "cunt" or "idiots". But that's only if I'm really heated about the subject, and I'm talking with someone close to me rather than in a school debate or something of the sort x.x But yeah, I don't find it funny, it's just sometimes it slips my mouth. The only time I found it funny was in the movie The Boondock Saints. :P
