To infuriate someone means to make them extremely angry, so furious they can barely contain themselves. It's stronger than just annoying or upsetting someone: when you infuriate people, you push them past irritation into full-blown rage.

Imagine your little brother deleting your saved video game file right before you beat the final level. That doesn't just bother you; it infuriates you. Or picture working carefully on an art project for hours, only to have someone carelessly spill juice all over it. That kind of thoughtless action can be infuriating.

When something infuriates you, you feel that fury building up inside. Your face gets hot, your hands might clench into fists, and you want to shout or storm away.

People, actions, and situations can all be infuriating. A friend who keeps breaking promises might infuriate you. Waiting in a long line while workers stand around chatting can be infuriating. The feeling is like an explosion of anger when something feels deeply unfair, disrespectful, or wrong.
