hump rash 

n) The resulting rash left between the tops of one's thighs after a prolonged hump (hike). Legs rubbing together, with the addition of an abrasive such as denim or a similar heavy fabric, removes the top layer or two of skin leaving a red, uneven, and sensitive hump rash.

Not always noticed during said hump (due to adrenaline) but becomes immediately obvious once you step into a hot shower.

Can be prevented by wearing compression shorts (Spandex) in the place of your standard undergarments (boxers or briefs).

The difference between a hike and a hump is that a hump involves carrying gear. One can hike with a day pack, a water bottle and a camera. One humps when they are carrying items of greater density such as tents, field rations, ammunition for the mortar and a rocket launcher used for destroying enemy tanks.

"We had a 20 miler yesterday and when I hit the shower I realized I was sporting a harsh case of hump rash."

G-Rash 

Father of K-Rash and B-Rash. His favorite pastime is to stand out on his driveway and smoke cigarettes all day, while bitching at people for little or no reason. Thinks he is a car and computer expert, but really doesn't know shit about either. Also owns a motorcycle, and looks like a fool when he rides it once every month.

G-Rash is #175 on the garbage list

Road Rash

The red, raw area around your mouth that comes from making out with someone who has lots of facial hair. Some people consider it to be a badge of honor. It's been acknowledged in some scientific communities that Road Rash was once a sign of nobility.

Cheryl: Kenneth gave me some serious Road Rash last night. It feels like his beard peeled 25 layers of skin off of my face. Awwwww'right.
