See my post of Tue 11:33am EST, where I argue that minhagim are grass
roots and just arise mimetically. They may (c.f. Rambam Mamrim 2:2)
require validation from a rav after creation to qualify. But I'm not
sure. E.g. the Ran says minhag is binding as neder (derabbanan; built
through chazaqah) and the Rambam says (according to RMSoloveitchik)
the problem is perishah min hatzibbur -- neither relies on rabbinic
authority.
