Men who ride Harley's or other cruising type bikes, who wear turtle shell style helmets because they are not driving fast enough to need a full helmet usually. And they ride on a bike that has had custom steering handles installed. The handle bars are usually raised an additional 10 to 12 inches, making the rider appear to be hanging from a monkey bar.
"How bout that turtle shell on a monkey bar, his tiny helmet had huge skulls painted on it and he was barely able to hang onto his monkey bar because it was almost too high..."
A bath that is extremely cold and causes the males penis to shrivel up like a turtle. Usually taken for injuries or fevers. Only can happen to a male since they have penises.
I had to take a turtle bath last week to help my fever go down, my junk was practically gone since it was so cold!
