A bloob, according to the Urban Dictionary, is "blue boob" found in the movie Avatar.
Consider a bloob. Because it is a bloob, and ALL bloops are toogs, it must also be a toog. But if it is a toog then, because no toogs are goopers, it cannot be a gooper. So if it a bloob it cannot be a gooper. That is to say no gooper can be a bloob.
a blob originated in France as 'bloob'.
