Ah, yes - the old F.O.P. acronym. Er... well, it goes this way: many years ago we took the kids to Florida to DisneyWorld; probably the second or third trip down, probably second as they would have been old enough at that point to recognize the many many cars off to the side of the road - main highways.
We asked somewhere about why so many accidents and the waiter leaned over and whispered in my ear "It's all the F.O.P.s around - Fuckin' Old People. They drive into each other, and us, and off the road all the time. Watch out for 'em."
Well, the kids thought this hilarious and I have been forever since referred to as "The F.O.P." particularly after that particular trip down where we just could not get the signage right to end up back where we wanted to go; there was so much construction and crap, we had been in the park all day, tired, cranky and very very hungry. Kept following the signs we thought we were supposed to take but ended up miles away. Back on the highway again and again and again and never did make it home.
Finally, saw a Chili's and stopped there. Had a couple of beers and a big f'n taco and got detailed directions from the waitress on how to get back and were home in fifteen minutes whereas we had wandered for over an hour before... Yup - F.O.P. it was from then on...
