First coined after Brookline High School Headmaster Dr. Weintraub used the term yeasty ad nauseum during his graduation speech for the class of OH NINE. The bronze, leathery-skinned headmaster meant for the term to imply "youthful" but as his presentation was nastier than christy allie's taint, "yeasty" soon became synonymous with something unpleasant or disappointing.
