Mommy made a mistake

I was in the car with my friend yesterday. We were trying to get to a store and she made a wrong turn. We had to turn around and her 2 year old son asked what was going on from the back seat. Janene explained that she made a wrong turn, and we were turning around. Willis responds "Mama fucked up." It took us a second to realize what he had actually said. But once we realized - at the same moment - it sent us both in to hysterics. Janene turns to me and says "Did he say what I think he just said?"
