Cooper moment

A moment in which someone says or does something dumb/stupid

When you tell a group of people you could totally do something you definetly could not do. Often refering to beating somebody in a competition, or a fight.

A brief moment in the simplest of terms that's an absolute pinnacle of a rambucfuckelis, swiggly niggly, whiter than cum on coleslaw moment by a nigglet named Cooper that is the devourer of the Arby's and has the nuttest of sacks for a chin.
