Didn’t they call it “jeep ass” or something like that, I know 2 people, a guy and a girl, not related, that had to have surgical treatment for polinoidal cysts when they were in their teens.
My niece had to have the operation. I wish I’d known beforehand as I might have helped her avoid surgery. Treated myself with no further problems.
“Jeep ass?” Wouldn’t surprise me!
