Ask Me Anything.
A Livejournal community, along with many branch-offs including AMA Offtopic, AMA vlog and AMA film.
It is lead by the Livejournal user UnknownJ and has many posts every day relating to every topic under the sun, including sex, clothing, body modification, relationships, food, and many other odd topics that can't even fit into their own category.
Unknownj has made the community with some ulterior 'plan' in mind, but as of now, what that plan consists of is a complete mystery to even the most active of AMA members.
It's where all the cool kids hang out.
Person One - Wow, Carrie from AMA is HOT
Person Two - Yeah, I'm going to go chat her up in IRC
