Angle of the Dangle... Refers to the Angle and size of a woman's breast while applying cocaine to them to generously snort, while gaining the bonus of having your face on boobies.
AOD can also refer to a game where (typically coked out guys) will pretend to pass out (slowly falling to the ground) but stopping themselves before ever coming in contact with the ground, it's kind of a "who's balls are bigger" test, which can go badly if you don't control your AOD, you can end up on your face.
Lisa has great AOD!
<pretends to fall> OH DAMN Tim, GREAT AOD!
