* Readiness: The food is prepared and waiting.
* Urgency: The speaker wants people to come and eat now.
* Abundance: There's enough food for everyone.
It can also be used more generally to signal that something is available and ready to be taken or used. For example:
* "The new toys are here! Come and get it!" (meaning the toys are available for children to play with)
* "The competition is open! Come and get it!" (meaning the competition is ready for people to participate in)
In essence, "Come and get it" is a powerful, straightforward way to communicate that something desirable is available and waiting to be claimed.
