vulgar, customs, manners, worldliness, mundane things
俗 centers on the ordinary, everyday world of common people: customs, manners, and mundane things. The sense of vulgarity comes from the idea of being unrefined or worldly rather than elevated.
俗 combines 亻 (person) with 谷 (valley), suggesting the common ways of people in the valleys—everyday customs and worldly matters.
A person 亻 in the valley 谷 represents the common folk and their everyday customs. The valley is where ordinary life happens, away from the refined heights.
For ゾク, imagine a zoku (a made-up word for a group of common people) gathering in the valley to share their customs: zoku -> ゾク.
