The bag (girl) that you donât want to fumble.
The âbagâ comes from the phrase: âFumbled the bagâ, which is used to express the scenario of someone messing up their chances of getting with a girl. If a girl is worth going after, then she is a baddie. But a girl who is a rare form of baddie, the girl who plays the role of the bag that you especially donât want to fumble, then she is a baggie.
Person A: âHe def lost his chances with her.â
Person B: âFr. Sheâs a real baggie, man.â
