2. A clever insult used to describe an annoying person, like a wicked itch on your nads.
"You're a Jock itch!"
"My computer is slow. It's being a jock itch!"
Jock itch was said by Bill Cosby to be "better than a good woman", referring to the utter relief found by uninterrupted scratching to relieve the nasty itch.
2. The yearning to be an athlete by a physically unremarkable nerdy kid.
The origin of the itch occurs as sweat, oils, and dirt are rubbed between the junk and the thigh. This forms "Duck Butter." Duck Butter, when at the proper temperature, is feasted upon by fungus. As we know, fungus grows in dark, moist, and temperate conditions. As this fungus grows, the leaves and branches tickle the the areas around ones genitals and creates Jock Itch.
