Cuttin’ A Rug
If you think that Southerners enjoy chopping up their carpets on weekends, you might need a bit of clarification on what “cuttin’ a rug” means. Southerners love to dance, and greatly appreciate it when someone can move gracefully or skillfully. Someone that has “moves like Mick Jagger” might also be described as cuttin’ a rug. This refers to the dazzling footwork that a person would perform on, potentially, a rug. Perhaps if someone had to wear a particularly sharp pair of heels when dancing they could actually cut a rug.
Whatever Floats Your Boat
Sometimes, you just have to let people do as they please, even if you disagree strongly and have done your best to convince them otherwise. When a Southerner realizes that they cannot convince someone to see things their way, they will end a debate with, “whatever floats your boat”, meaning, “do as you please”. You could also say it when someone wants your approval to go through with a plan or activity. If you happened to be watching an intense football match, and someone asked you if they could borrow $200, you might be too distracted to consider what they just asked properly and respond with this expression.
