Herpes of the mouth. Not to be confused by oral herpes, which is entirely different, obviously.
Its main source of distribution is the swapping of generally similar looking bottles.
Sue: Hey Sam, I may have misappropriated my bottle and it looks like yours.

Sam: Oh no, perhaps you now have mouthal herpes. That is not fun.
