I think Fredneck would play off of the whole; You might be a redneck if/Jeff Foxworthy thing. On one of the other threads someone posted a slew of “You might be a Fredneck if...” lines. This might, IMHO, backfire though — as in painting Fred as a ‘redneck’ in the bad sense...
[Living in Wisconsin I would prefer being a Fredhead than a ‘Cheesehead’. I’ve always found the Cheesehead moniker a little condescending... Of course, that could be because I grew up in Illinois. LOL (o;]
