ammo

Ammo is short for ammunition.

When we talk about ammo, most people think of bullets or shells used in guns. But it's also common to use ammo to refer to any sort of supplies that help something run smoothly, like food for animals or even fuel for a car. In gaming, players might collect ammo as a power-up to make their character stronger. The word is usually used in informal conversation and can be heard in movies, TV shows, and online content.
