We were driving somewhere from CT down to TN I think, and on the PA map(I think) there was a town called "Frackville". It stuck in my head. I wish I could say I was from Frackville, what a claim to fame that would be! As for the usage of the word "Frack" I started using it heavily to replace a certain swear (I have the mouth of a truck driver). Although, I gotta say, "frack" isn't nearly as frightening as the word it replaces. I let it slip the other day, I asked my brother what the frack he thought he was doing (he was attempting to use my Powerbook, which he has been banned from since he chucked it across the room). Needless to say, he wasn't exactly cowering in fear.
iGary's posts are good for new vocabulary. Asshat, anyone?
