An abbreviation for Just the Right Amount of Information; a spinoff of TMI (Too Much Information). JRAI is used in the same context as TMI, but to preemptively imply that one might consider the information given to be TMI or an "overshare," however the speaker disagrees and thinks that it is just the right amount of information and not too much.
JRAI can also be used as a sarcastic TMI as a response to something you didn't want to hear being revealed.
1. Yesterday I had explosive diarrhea. I know, JRAI.
2. A: "So then me and your brother totally boned."
B: "Oh, JRAI."
