Pee-Wee Defense
The Peewee Defense is the defense employed during an argument by somebody who is bad at debate (or is trying to argue a really stupid point), generally when all other forms of defense have been exhausted or they otherwise run out of options. It consists of one individual attempting to turn the debate against the opponent by accusing them of the exact same statements being used by the opponent.
"Only an idiot would rely on the Pee-Wee Defense to win an argument."
