Hi Outhouse Man, oops, Ray: You have earned your alternate name!
Many years ago, when camping in the Washington Cascades, my daughter and I found a lovely remote campsite, a one campsite campground! With only one campsite, and next to no other cars on the narrow dirt mountain road, there was little concern for privacy. Then we discovered it had an outhouse, but it was different: it had an "out" but no "house". Just the toilet seat elevated above the ground surrounded by the great outdoors. It was not visible from the road nor from the campsite unless one really worked at it. This resulted in a new term in our vocabulary. We're going to the "out". So now when a last minute trip is needed before heading somewere, we'll often hear the expression, "I'm headed to the "out", and it is totally understood.
Your tale of headbumping, while providing a trip to the dermatologist for you, brought back many wonderful memories for me of an "out" without a house.
