Jack: "Can people bust?"
Me:"What do you mean? Give me an example."
Jack: "Well, it's when you sneak up on a person and throw them in jail."
Me: "Oh, you mean getting busted. Yes, that is a phrase people use to say that someone got in trouble. A person has to do something really bad to get busted and put in jail.
Jack: "Yes like if a person was lying or doing something bad."
Me: "How did you hear about that?"
Jack: "Well, this kid at my school, he's really smart and he knows all about it and he told me that's what busting is."
