My chapter is kind of guilty of using these terms. We only doing it mockingly however, but we probably shouldn't. Like one of my fave sisters said once "Yeah I tell people I'm a sorositute in a whorority", and I have a picture of a group of us at one of our events and we all showed leg for the photographer and the sticker I put on it in a bubble says "Welcome to the whorority girls". My apologies if anyone is offended, honestly.
