The original term was made as a response to mock misogynists and incels who got angry when they encountered women calling them out for sexism or double standards. Its use was similar to that of "drinking your enemy's tears." Meaning that the term was not mean to be taken literally.
The term "male tears" was hijacked by incels in Urban Dictionary after women started putting the words "Male Tears" on mugs, implying they drank the male tears of misogynists for breakfast. Apparently, some guys didn't like that too much so they defined "male terms" in Urban Dictionary as "semen" in order to scream "gotcha" at women who call out men's bullshit. Because of course, the only way to degrade a woman is to slut-shame her and make it seem like she is implying that she drinks semen.
So no, "male tears" does NOT mean semen in its original context (memes). It was simply defined that way in Urban Dictionary because "Har har, wouldn't it be funny to make it seem like empowered women are drinking our sperm when they say "I drink male tears" instead of making fun of us because of our fragile egos???"

A term that has been used since before 2012 to mock how much entitled men cry when women do or say anything that makes their sense of privilege feel even slightly threatened. But that in the last couple of years, men have attempted to change to mean sperm (even though there is no evidence of the term ever having been used for that previously). Because they have to undermine every single thing that women do.

the term 'man tears' has been used very rarely to mean sperm. But it is a different term to 'male tears' (the clue is in the way the words are not the same), and even that had originated with another meaning before being hijacked by sperm-obsessed men.

It means sperm, according to some men. Men whose testicles are hanging under each eye. That's sad.

A term used by feminists who wish to exhibit how un-bothered they are by the protests of men who feel threatened by feminism, or by her individual independence. Used to show how they do not care for the unasked for opinions of men.
