DH says shite, but just because that's what he learned first, I think. It sounds odd, because he doesn't have a South African accent at all.

Eta: on further reflection, he uses both "shit" and "shite" with slightly different meanings. He'll describe something that's nonsense as "utter shite" but if he hits his thumb with a hammer, he'll say "Aynar! Shit!"

I can't remember where I picked up "shite" -- probably Trainspotting. I'm sure it sounds affected, but since I really am using it completely unconsciously, I can't help it.

I really am using it completely unconsciously, I can't help it.

This is me, too. I don't use it often but sometimes it just pops out.

It can be cheesy, I guess. I swear like all the places I've lived, so "shite" pales in comparison to "tabernac" in terms of incongruity with my accent.

See now, tabernac I like. It would be such an obviously intentional usage that it escapes the twee factor, for me.

I've seen various Kevin Smith movies uncensored, so I'm going to say yeah.

I've seen them censored occasionally and it's just pointless. Just about everything out of Jay's mouth is overdubbed with something really stupid.

I use friggin' a lot, even when I'm not self-censoring. I seem to use it for emphasis when I don't think something is quite f-bomb worthy.

I also tend to use "Fun" in a sarcastic tone of voice when something bad, but not overly surprising or tragic, happens which people have sometimes mistaken for "fuck".

"Fuck a duck!"

My friends and I used to use this one a lot in highschool. We almost died when one of our quieter female friends heard one of us exclaim it and replied in a sultry voice "Quack, quack, baby."

At some point later it evolved into "Fuck a duck with a rusty chainsaw!" but I have no idea why. I just remember that this indicated that the situation was more unfortunate than those that invoked ordinary mallard copulation.

"Fuck a duck with a rusty chainsaw!"

I'd guess from Heathers ("Fuck me gently with a chainsaw").

It would be such an obviously intentional usage

Except it's not obviously intentional. No more than the rest of my swearing, anyway.

I'm sure it sounds affected, but since I really am using it completely unconsciously, I can't help it.

Yep. Same for me, along with "bugger", "bloody", and "wanker".

I prefer frell to frak, but only use them in my head. I just can't convincingly pull off potty mouth.

Yay for new phones. I got the Sprint Treo variety. Sadly I haven't taken the time to set up many of the features. I haven't even used the camera, but the kids have.

I'd guess from Heathers ("Fuck me gently with a chainsaw").

Could very well be. I do think that was quoted at least once (though I never saw the movie until well after highschool) and over time they just sort merged into one uber-exclamation.
