Once your gouch gets sweaty after intense and/or prolonged exersize it becomes extremely bothersome and uncomfortable. One would say they have become tired of dragging their "sweaty gouch wagon around". Not until the gouch area is washed in a cold shower can people continue to tread all over your gouch. - Particularly prevalent with the use of compression shorts.
Tony: Ah my gouch is so sweaty i need to shower!
Jebediah: WELL SOUNDS LIKE YOU WORKED UP A BIT OF A GOUCH WAGON!
Tony: Indeed I did, I can't drag this gouch wagon around with me everywhere
