Colloquially, the term baggage has been thrown around to mean that something is wrong with a particular person or their ways of reacting to a situation. It signals that past issues are at play and the person in question has not managed to get over it. The interesting thing is we all carry around baggage in unexpected ways. Some forms are even socially acceptable. Take for example, society's collective disdain for "the ex". We've all seen the memes, you know the ones that depict picture perfect pettiness (for reference, please see examples below). We chuckle or actually laugh out loud at these because 1) They are, in fact, hilarious; 2) They perfectly capture all our feelings about those past situations; and 3) They identify, in exaggerated ways, the justice we feel they deserve for causing said pain.
