A molly ball (or mollyball, one word) is the pure form of the chemical MDMA (commonly referred to as ecstasy) which has been rolled into the center of a ball of some type of food and then eaten. This may include, but is certainly not limited to:

-Brownies

-Cake

-Rice

-Bread Dough

- Dinner Rolls

-Spinach

-Macaroni and Cheese

-Spherical Empanadas

-etc.

In addition, 'Mollyball' may be modified to become the verb "mollyballing" or "playing mollyball".

The word itself may also be shortened to either "MolBall" (pronounced 'mall-ball') or "MB"s.
