breast brei

The white fungus that grows under a woman's breast when she is not wearing a bra and forgets to clean herself on a regular basis.

I hate the way breast brei tastes.

breast reduction

This is one of many pointless processes, such as gay pride parades, RIAA watching of file-sharing, etc.

She told me that she wanted to have a breast reduction even though she is a 32B cup, and I told her she was wasting her time.

breast nystagmus

Involuntary jerking of the breasts; often times said when a breast is in motion due to the owner's physical movements.

If she runs fast enough, she will show breast nystagmus to the crowd.

Dense Breast

Like bags of sand. Often mistaken for implants, even on close inspection. The bane of mamographers everywhere.

Break out the MRI, we've got a real dense breast here.
