1. The raised line running sagittal along the median of the scrotum. Formed prenatally in the first trimester when the potential labia fuse together. Most notable after swimming in cold water. So named because this is where Jesus "welded" the scrotum together.
2. That line on the nutsack going from the gooch to the dons.
