ranting

Ranting means talking loudly and angrily about something, often because you're really upset or frustrated.

When we say someone's ranting, it usually means they're going on and on about a particular topic without stopping to think about how others might feel. Imagine you're at the grocery store and there's a lady yelling at the cashier about a bad piece of fruit. She's not just talking loudly, she's actually ranting – her words are flowing out in a kind of angry stream. Ranting can be entertaining to listen to for a little while, but it can also get really annoying when someone rants on and on without taking a breath.
