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.
