Guys that wear tight pants, usually the really hot skateboarder types, are stupid and inconsiderate. They are selfish, hard to deal with, and extremely forgetful. The tighter the jeans, the worse the guy.
The Tight-Pant Rule in action:
Tight-pants-wearing Guy: Yeah, I'll call you at seven!
Girl: Okay sounds good!
Girl: Why didn't you call me?
Tight-pants-wearing Guy: Uh I forgot.
