Fat rape girl

Rape girl began as a thread on 4chan where an anon posted a picture of a fat unattractive girl who was protesting against rape, with a sign says "this is not an invitation to rape me" and while she was wearing a low cleavage shirt.
It followed by many sarcastic people editting the photo to make fun of her and the fact that she is fat and ugly and therefore will not be raped anyway. Also, it was easily transformed to be making fun of feminists as well.

Other than being a joke about the fat girl, the photo is used when sarcastically expressing or protesting something which will anyway will not occur or the person with that statement is the only one thinking so. (i.e the girl is wearing a cleavage and by that protesting against rape, though no one will rape her)
