The point where you hear Bono preach the same thing more than once.
"No! That's enough, he's getting bonotonous now."

The state of extreme, monotonous boredom, usually associated with study leave and exams. Extreme boredom Leaves you spending days on end in your room, revising, chatting on msn, and making strange words on urban dictionary.
"Man, this revising sucks, im so f**king bonotonous, im gunna get off msn and watch some paint dry."
