Perch AIDS

A disease contracted by getting sprayed in the face by the milt (or semen) of a yellow perch while removing a hook from it's mouth after catching it. Fishing for perch is not normally a dangerous activity. If you or a friend gets hit in the face with perch milt, you will forever have "Perch AIDS". There is no cure.

"My buddy went fishing today and caught some perch! He also got sprayed in the face by fish cum, so he now has Perch AIDS forever. Poor bastard."
