Do Not Pass Go

"Incarcerated" - Why is it that the only people to use this word are either those that are in jail or their relatives?  Come on!  Could it be that it's the only 5 syllable word you know?  Admit it, you are in jail, in prison, in the pokie, locked up, in the hoosegow, tossed in the brig, in stir, in the big house, or been sent up the river!!
