box butt 

The intense numb, compressed feeling one gets during an extremely long car ride with no stops-- akin to one's foot or leg falling asleep, except in the gluteus maximus. Can be cured by getting out of the vehicle and walking around and stretching. Origin: misspelling of Box Butte County, Nebraska

Everyone had a severe case of box butt when stepping out of the car in Montana: the last stop had been in Minnesota.
