In the American mid-west it's fayverit.
By the way, I'm sure you Brits aren't getting that southern American accent right because you say almost everything in front of your molars and you open your mouth tall by comparison. Southern Americans bite everything they say, and say anything they can be said behind the molars. And when more space is needed for a given sound, they go wide instead of tall. Try it.
Makes me wonder if socio-economics has an effect on linguistics, seeing as most southerners come from stock that was once poor and desperate (after all, they were desperate enough to leave merry England).
Ummmm...... I assign ....... um ..... weird (for me) timezones for playing werewolf.
