“Bluris is a chup”
I have heard many shiurim from Rabbi Reisman Shlita, where “bluris” has come up, and he goes out of his way to point out that what the gemara/halacha refers to as “bluris” is not what we commonly refer to a “tshup”. It is more like a pony tail, as a bluris is something that comes across the top of head towards the back. (Do not infer from this anything regarding Rabbi Reisman and a growing tshup)
