To use when talking in spades and not swearing at the same time people would often say 'flick' instead of 'fuck'.
The municipal government of Toronto once questioned a campaign to influence people to say 'flick' in stead of 'the f-word' as said in a saturday's newspaper on april 28th 2007.
"That is some flicked up shit right there!"
"You flickin' idiot!"
"NO FLICKING WAY!!!"
"I just flicked her last night ;)"
