to claim something first · to call first on something
What's the situation?
Imagine you and your friends are shopping, and you spot that *one* perfect item everyone might want! 🤩 This is when you shout "Dibs!" to claim it as yours first! 🙌 It's a fun, informal way to reserve an item, whether it's the last piece of cake or the coolest jacket on the rack.
