My sister and I got into an argument on the phone about the money she owes me, but a few hours after we got off the phone I sent her a text asking "So...are you still mad at me?" ...She simply replied "IAG!" and I knew we were on good terms.

An acronym for "it's all good." Commonly used to make peace during a misunderstanding. Also applicable when accepting one's apology. And on occasion, used as sarcasm.
Friend: Man, I'm sorry I used all the toilet paper...
Other Friend: Nah man, don't worry bout it, iag...just put more in the bathroom if you run out.

Alternate Response (sarcastic): Nah man, don't worry bout it, iag...I love smelling like crap all day because you can't replace the roll!

MJ-Authentication

This is similar to the TCP/IP syn response during the setup phases of the 3-way handshake process. This response is specific to MJ-Authentication from the M party.

ik and iag are of the mjml protocal standard
MJ-Authentication

J sends ik to M
M send iag to J

When both parties receive this symmetric key authentication has been performed and communication can safely continue.
