The horrible disease that infects every single red haired person. Symptoms include: red hair, freckles, the lack of one's soul, and the feeling that you just don't belong in society. Gingervitis can be passed on to other people with the harmful bite, this bite can spread the disease to any person, so be careful around ginger kids.
Andy : dude did you see that soul-less ginger kid?
Eric : yeah, he definetly has gingervitis, don't let him bite you.
A disease carried by a person/ginger with red hair. Once contracted it is not curable. Contracting this disease is as easy as kiss a ginger. If the person has dyed red hair they do not have the disease. This disease is highly spreadable and is genetic.

Boy(ginger): welcome to the wonderful world of gingervitis.
