A phrase used to win an
argument. After said phrase is spoken, proceed to punch the opposing person in the stomach. The phrase was first coined in
internet personality Linkara's review of the god-awful DC Elseworlds story "Superman: At Earth's End," when Superman (looking an awful lot like
Santa Claus) shouts the phrase at chicken-headed android Ben Boxer, and then proceeds to punch Boxer's guts out.
(walks up to
random person on the street) "I AM A MAN!!!!!!!!!!!!" (punches said person in the stomach, possibly rupturing his/her
intestines)
And yes, even if you are a woman, it only works if you shout, "I AM A MAN!!!!!!!!!!!!!!"
