A non-scientific term used to explain the biochemical phenomena known recently to modern scientists as "adipose-eruptis". This term is generally applied to lab test subjects who have generally imbalanced hormonal environments(too much estrogen and not enough testosterone), in order to find out the limits of flesh accumulation. Known to lead to high cholesterol, blood pressure, diahria, stomach discomfort, air pollution, toilet overload and other misc. unpleasantries.
The highly famous scientist showed the crowd how his bulkus test subject could not run for over a minute on a treadmill.

one very insecure individual, who normally takes up 2(up to a rare maximum of 4) plane seats. Generally has a BF of > 20%, however due to androgen hardness convinces most of his fellow peers, and especially himself, that he is sub 15%. This condition is generally hard to get rid of, and is only possible through anorexic obsession. Often known as anti-anorexic insecurity syndrone.
