The name of the first Herpes that appears on a mouth. The name hails from the character "Frank" on Its Always Sunny In Philadelphia because it looks like a little disgusting sick fuck hanging around your bar (Mouth). All additional herpes follow the rest of the Its Always Sunny In Philadelphia cast members. So for example: the second herpes to appear is named Dennis, the third herpes is Mac then so on and so on.
