ballseam

The wrinkly skin that separates the scrotum into the left and right hemispheres.

I was freeballing and my zipper caught my ballseam.

ballseam

The line where the two halves of skin join on a scrotum

I love the way your ballseam runs up to the base of your penis splitting your balls between left and right
