Doorjam 

An alternate name for the cupholder below your car's door handle, specifically the one in the front seat. Combination of "door" and "jam" because nothing fucking fits in them.

Ron: "Hey Billy, why are you holding your water bottle on your lap?"
Billy: "Because the doorjam is too bloody small to fit it."
