nystagmus

Rapidly, involuntary eye-jiggling.
The real name for the eye-wobbles that you get from taking ecstacy.

Nystagmus

It’s when someone can move their eyes really fast and basically twitch them side to side. It’s a genetic mutation. And asking someone how they do it is like asking how someone can move their finger. I have this mutation, and it can limit eye sight and gives the person a higher chance of having really bad vision.

Person 1: Yo how are you doing that with your eyes?

Person 2: Oh I have Nystagmus, a genetic mutation.

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.
