A disease obtained by the highest level of whore. (Level 60 Warlock Whore). Can be contracted through any oriface, but leads to big ass nasty sores all over the body. The result of this disease is imminent DEATH, or at a minimum some really nasty scabs and scars.
ie: Dirk Burkster was with this dude the other day and that Mofo gave him FBH (Full Body Herpes).
"Mom, I have this burning sensation when I pee and all these sores all over my body."
"Son, thats because you've got the Full Body Herpes."
