Master Chief Syndrome

An often overused antic in modern culture where one man (or small group) face incredibly overwhelming odds and win. Generally only met with "dude" and "sick" from bro's and frat boys, and met with chargin from people with brains.

"Dude Master Chief just jumped out of a space ship and blew up that other ship. Then he single handedly killed 4.5 million aliens with his bare hands... sick."

"That end fight in Saving Private Ryan was such an obvious case of Master Chief Syndrome I'm suprised anyone can keep a straight face."
