AOTD 

Album Of The Decade. An album so good, it will take at least ten years for something better to come along.

Pink Floyd's "The Dark Side of the Moon" was definitely AOTD in the 70s.

AOTD 

an acronym for Asshole of the Day, a daily award given to the person who has been the biggest asshole in the past 24 hours. A number of behaviors can win one AOTD. These actions include but are not limited to: being an asshole, raw dogging, ditching your friends, driving drunk, performing a bus flip, and wearing sunglasses when it's cloudy and overcast. Not to be confused with AOTW (Asshole of the Week): a highly coveted award among assholes everywhere

After getting drunk and raw dogging someone else's girl, he was awarded AOTD.

You're in the running for AOTD right now!
