Katie's Blackburn
A terrible STD discovered in 1992 among the lesbians of Pittsburgh. It is extremely foul and lies dormant until disturbed, but once awakened, its wrath is unstoppable. Characterized by turbans and outfits worn the previous night. Often becomes delusional when fed alcohol. The only known treatment is sex with straight women.
Don't wake Katie's Blackburn, pee in the alley!
