procrasta-masta
Someone who is really good at procrastination. They habitually do it, often staying up until the wee hours of the night, if they sleep at all. They never learn to do work steadily or early. Yet somehow they always get it all done! AND do it well!
Man, how does Rob do it??? He didn't start his report until midnight, didn't sleep at all, and he still gets a 98%? He's such a procrasta-masta!
