Muskeg dick 

A condition caused by constantly being submerged in swamp water. Symptoms of which include itchy red swollen feet, and loose fibers within the urethra. A pre-cursor to this condition may also be seen as boots filled with muskeg.

Ex. Mom I think I got the muskeg dick.
The other day I was walking in the swamp and seemed to have contracted the muskeg dick.
