I know! Right?!

It's pretty clear what the speaker is trying to convey: "I agree."

I agree with most of the other definitions, which provide details on the subtle context/audience-dependent connotations. I agree that phrase is annoying, used by speakers who use other annoying phrases like "my bad."

I would like to add to what has been said by providing side-by-side analogs; that is, alternative, equivalent but more acceptable expressions.

That's all I know.

A term used in the Mid-Western region of the United States, particularly Eastern Missouri. The term is used to end a gossip session or other verbal engagement between Two or more people. It is spoken when the speaker is ready to disengage from the conversation or has no further information concerning the topic of discussion. It is also a common signifier that the person using the term is done engaging in general conversation with another person.

Also, Sarah has her bridal shower and she wanted me to give you that info. Well, that's all I know.
