Fuck's definitely one of the more satisfying ones, though I like to mix it up a bit. Y'know, shouting things like "you fuckin' ARSE-BANDIT!" or "FUCK-MONKEYS" is waaaay more satisfying than just using fuck.
AWWWWW SSSSSSHHHHIIIIIITTTTTT is my personal favorite cause it can be used for positive reasons, like when someone with mad skills totally takes someone's chump ass to school or when something JAWSOME happens that isn't expected.
Yes, those are quite my favorite, if I do say so myself. *Sips a spot of tea*
You SHITFUCK. or, alternatively, what a fucking cunt. Although it makes me laugh when ladies get offended when I say that. I always say: You'd call me a bastard or a cocksucker in a second. It equals out you twat.
Fuck, in all it's forms just rolls from the throat the best.
It's a fucking ideal word for any situation where other words just seem to be lacking. As such I use fuck at least 4 or 5 times a day. Empowering words, cussing, expressing surprise, expressing joy. It's awesome.
Having said that, variety is the spice of life, and I do use other "powerterms"
