unspoken rule

Silent social contract

An unspoken rule is a behavioral expectation understood by members of a group but never formally stated: There's an unspoken rule that you don't take the last donut without asking.

Such rules govern workplaces, families, and social situations—often more powerfully than written policies.

Violating them typically brings social disapproval rather than official punishment.
