28 years ago, around the table one day by lunch several guys in the yeshiva were discussing the terms applied to groups of yidden. Back then, if you wore brown pants and a blue shirt (at the same time) you were “greasy”, if you wore a belt (gevald!) You wore a bit to the left. If you were color coordinated, gevald, you were already halfway towards kefira. Times sure have changed. Super greasy (the term yeshivish wasn’t in the vocabulary) guys didn’t take off their hat and jackets in the bathroom or, while playing basketball.
That was the psak of those bachurim in yeshiva of staten island, all those years ago. 🙂
