IAG
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!
