It's an age old saying but what it really means is "Why aren't women really funny to guys?"
Another translation is:
"Guys are really funny to girls and other guys."
but
"Girls are just funny to other girls."
It goes without saying that the majority of comedians are guys. To me, I haven't genuinely laughed at any female, trying to be funny, in my ENTIRE LIFE. Every time I laugh, it was either fake/forced.
After thinking about it, is a bit unsettling and scary because it is real one way street. Like how only women can get preggos.
Why is this?
