I call it the Women who nobody wants to grab by the pussy march.
This does not seem like a joke that would be taken very humorly.
I believe it's just a joke that a bunch of trash feminists just arranged to have fun.
It is pretty mean to talk about a women that people do not find attractive. This is very insensitive to say that there is nobody who would be attracted to a certain women, and could make the person very upset. It doesn't matter exactly who created the joke, it is still mean.
