The epitome of awesomeness. a Celebrity at Cornell University who is famous for his charisma, social skills, hotness, intellectualism, uniqueness, stripping, dorm hopping, character, and the fact that he's Thunder Powell. He's just freaking amazing.
"That dude is such a Thunder Powell."
"Thunder Powell needs to put his pants on."
"Thunder Powell doesn't do push ups, he pushes the earth down."
