When one reaches a certain zenith of unbridled manliness, one cannot cry saline-basedtears anymore. Instead, one's tear ducts will secrete other, lesser men, who then proceed to cry in one's stead.
My friend John saw that Sarah McLachlan SPCA commercial last night and cried man tears.
White ManTears is when a white man commits a crime and blames it on insanity.
The Parkland shooter is a perfect example of White Man Tears. After his mass shooting causing 17 deaths he faked insanity in order to get a lighter sentence.
