Baggage

Everyone carries their own history. This may also be referred to as "baggage." Somebody's reputation is their baggage. If you have been married three times already, and are looking for number four, then number four must know that you bring with you a great amount of baggage, a "backstory" as they say in Hollywood.

"What's your bag?" is a slang way of asking, "What are your interests, what do you like to do?"

What's in my bag?
