TV sports persons annoy me daily with this one:

Ath-a-letic. As in, sports fans and athaletic supporters.

A local one which is kinda funny the first zillion times you hear it:

fidgiderry

Got it yet? Whatever you were thinking, likely that's not it. It's refrigerator. Seriously. It is a corruption of the brand name, Frigidaire. That first R apparently is impossible to see, but is made up for by pronouncing the E. Written spellings, too, are quite exotic, including "frigerotor".

Ain't langidge grate?
