Clittosaurus Rex

It is basically an insult that can easily enrage people of the gender known as female, because it implies that their clit is the size of a penis! Hence the "Rex" since the T-rex was quite a large dinosaur. It comes down to calling a girl a shemale.

OMG P**** raped me up the ass with her huge clit! She's such a Clittosaurus Rex!
