(Noun) A guy who doesn't show up when you're out with boys for a cool one.
Chuck didn't make it to tailgating 'cause his Chevy Malibu broked own on the way to the game. There was definitely a hole in the brozone layer last Sunday.
The so-called "Bozone layer" is a thick, impenetrable shroud of bozone that surrounds all intelectually challenged people. When an bozone layer appears, it is hard to get rid of, and on the contrary it grows, blocking out all intelligent thoughts from reaching the victim. Though many tests have been performed, we have yet to discover a substance which creates bozone holes.
-Gee, he has a thick bozone layer!
-Huh...
-I wasn't talking to you.
