doesn't love the Lord and Southeastern Conference football

An ironic expression used by Southern males to express disbelief in or mild condemnation of some else's attitudes or behavior, supposedly drawing on some stereotypes of Southerners. (This expression possibly originated with Lewis Grizzard, a most excellent American humorist and commentator.)

Billy Bob eats strawberry Moon Pies and drinks Pepsi; only someone who doesn't love the Lord and Southeastern Conference football would do that.
