chatty

A chatty person talks too much and often about things that might not be very interesting. They love to share their thoughts with others.

When someone says "my friend is really chatty", it usually means they get into long conversations that can be a bit overwhelming for some people. You might have friends like this who dominate the conversation, asking questions and sharing stories without giving you much of a chance to talk back. It's not always bad, though - being chatty can also mean someone is very enthusiastic and energetic, and their love of talking can make others feel more included or entertained.
