AOA stands for after orgasm affection. First heard in "Marriage Boot Camp: Bridezillas" Season 1 Episode 7 "The Plunge" by Rob, husband to bridezilla Remy.
I figured since the other guys need help in those areas, I’d work along and I introduced them to the term: AOA. That stands for after orgasm affection. Don’t just roll over and sleep or get up and go make a sandwich. You gotta hug your wife, cuddle with her, show her some affection. Most girls love that, so I’m hoping I inspired some of the other guys to try it out.
