Stands for Optimal Breast Size. OBS is the point at which the female chest is near perfect in dimensions; they are neither too small or too large, as Goldy Locks would put it, they're juuust right.

Obes

A supernatural spectacle of nature that has transcended the known physical and mental limits of humans. Truly awe-inspiring. Not to be confused with a unicorn or chupacabra. Can and will drink fast, slow, in large quantities, in small quantities, forwards, backwards, upside down, downside up, right, left, diagonally, in the past, in the future, and in another dimension. The sky is the limit. A true badass, a remarkable individual, and a phenomenon of nature.

“I saw an Obes today.”
“Then your eyes have been blessed.”
