Slut rabies
Almost like getting regular rabies, but to get slut Rabies you must be bitten by, of course, a slut.

Get checked out if you have.
say a slut and a non-slut get into a fight and the slut bites the non-slut.

friend of non-slut: "oh wow, did she really bite you?!"
non-slut: " Yea, i hope she didn't give me slut rabies."
