You may use the contraction "y'all" if—

Nice people who are not Southerners sometimes want to use "y'all" and fear they can't because they're not Southerners. As someone who was born in South Carolina and raised in northern Florida, I hereby give you permission to use the contraction under these conditions: 1. You only use it as a second person plural. 2. You put the apostrophe where it belongs. 3. You don't use it to mock
