3/6 - Weird Hand AQ in BB

[AtlBrvs4Life]

UTG and I have been going at it for a while at this point. He's pretty much a maniac and we have been in multiple reraised pots together. He can have a pretty wide range here as he called my reraise with 87o earlier. I know nothing about CO. It's literally his 3rd hand on the table. What do I do?

Also, on a side note, I was wondering if a flop aggression factor of 6 is way too high?
