If someone is "loose with [something]," it means they aren't strict with it or use it carelessly. Ex: I'm very loose with my children's bedtime. They go to bed when they're tired. Ex: Hannah is too loose with studying for exams. She doesn't take it seriously. Ex: I'm very loose with my books. I don't mind when you return them to me.
