Greedy Fool; noun.
What happens when you reach the end of Central Processing, and instead of rushing through the exit: decide to wipe the last Blinky off your tail before it can chomp your neck off.
And then you realize you just swapped Chaingun -> Rocket Launcher instead of Chaingun -> Shotgun, and blow yourself back to the starting point.
