#11: “Quit Being Ugly”
In the South, ugly isn’t about looks but attitude. If someone tells you, “Don’t act ugly,” they’re not talking about your appearance but your behavior. The South prides itself on good manners, even when they’re not entirely sincere, so acting rude, mean, or disrespectful won’t fly.

This phrase is often heard from Southern mothers, scolding their children for talking back, throwing tantrums, or picking on others. It’s a gentle but firm reminder to mind your manners and carry yourself with grace—because in the South, being ugly inside is far worse than anything outside!
