boisterous

A boisterous person or group is loud and energetic, often in a way that's fun but also maybe a little bit annoying.

When people talk about something being "boisterous", they usually mean it's making a lot of noise or causing a scene. This could be a party that's getting out of hand, a child who won't stop shouting, or even a river that's swollen from heavy rain and is rushing along with a lot of force. In general, boisterous things are active, lively, and maybe a little bit overwhelming – but also often entertaining!
