How to name a custom multicolumn expectation

The How to create custom Expectations page mentions

Note: following Great Expectations naming conventions for Expectations is highly recommended, but not strictly required. If you want to confuse yourself with bad names, the package won’t stop you.

but there isn’t a page with examples of more complicated custom expectations.

For example, if column_A is “Inforce”, then expect column_B > column_C otherwise some other conditions. What would be a good name for this expectation? expect_multicolumn_to_satisfy_status_and_date?

Is there a convention on how long the name should be?
