When you're beating your meat so damn hard that you tear the surrounding penile skin and your penis looks like a peeled banana.
I saw bought Belle Delphine's bath water so I filled a bath and started beating my meat too hard and now I have a Peeled Banana.
A Skinned rooster is when the entire surrounding penile skin around the entire penis is just not there, gone. See Peeled Banana for more information pre-Skinned rooster
I had to get surgery done after Kylie gave me a peeled banana, now I am stuck with a Skinned rooster
