Constipation (Noun) The sensation of having to go combined with the complete inability to do so. It feels very much like you're trying to push a medium-sized troll out your sphincter sideways. Characterized by bulging neck vein, red face, and contorted body.

I dunno, folks. I'm not so sure your car is the best place to work through your constipation difficulties, but then again, that's why Tobey Maguire is a big-time blockbuster movie star while I'm just a guy who writes about them.
