Fantapubitis is the common name for Grade 2 Gingervitis
, usually manifesting itself from the age of 11-13. It is characterised by the growth of orange or ginger pubic and axillary hair. The development of this advanced stage cannot be prevented.
As with Gingervitis, there is no known cure and sufferers will mature at the same rate as normal teenagers. Fantapubitis is not sexually transmitted and so no additional precautions are required during intercourse (although you are a sick bastard if you do go through with it, and should probably have your head examined).
