The feeling of impending doom someone gets when you have exhausted all forms of entertainment available to you.
Someone would be considered brainnumb when they are sitting at home, has cable, an X-Box, and internet but just doesn't "feel like doing any of those things". He is also bored out of his freakin mind.
