A term for a rather large bra. The boobs are represented as the boulder and the over the shoulder holder represents the bra itself.
I was checkin out this chick at the mall. O man she was wearing this tank top and you could see her over the shoulder boulder holder. O man she had huge knockers. I wanted to jizz all over her face.

What my mom used to call a bra back when she was in high school, so like during the seventies. Often used when the bra is suppourting rather extreneous boobs.
Did you see that over the shoulder boulder holder that brod was wearing, she had some mean big boobs.
