When you're doing it doggy in the poop shoot and your arm is over her shoulder holding that boulder.

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.

That whale over there needs to put on an over-the-shoulder-boulder-holder to stabilize those breasts that constantly hit her in the face while she runs.

Unless you are a misogynist, do not ask any female how much her over-the-shoulder boulder holder costs.
