Hair Compensator is a guy who is going bald on top but grows a ponytail in the back. Also grows a massive beard to make up for lack of head hair.
Hey look at pony tail dude. Yeah, what a Hair Compensator...he went bald on top so he is making up for it by growing it long in the back. At least it's better than a comb-over Trump style !
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
