Maybe they made the mistake from misunderstanding something like "Fukin' A!"? There are times when *I'm* not certain if something is meant to be good or not, or if (as I gather from context) it's good, how. Case in point? "Bitchin'". The English speaking world throws around "Fucking" with enough abandon that I don't blame the Japanese for getting it wrong. No other nation would use something so misunderstood in advertising though... I hope.
