NL50 on HoldemPoker.

The only relevant stacks here:
CO (villain) - ~50
Me - ~39

Semi-loose somewhat aggressive player raises to $2 (standard 4x) from the CO. Major fish calls on the BTN. I have AKs in the BB and raise to $7. CO pushes all-in for the rest of my chips. I figure I'm probably flipping here, but still elect to call.

I called because I already have a decent amount of money invested, I can see all 5 cards, he most likely wouldn't push here with KK or AA, it's 5-max, and I have AKs. Is this a standard call with AKs?

A reraise when you have AK = fold in my book. Especially a limp reraise.

I think most of the time the a reraise of your AK is AA or KK and you just lost most of your outs. Few people would limp push with AQ or QQ.

There was no limp re-raise. CO did a standard 4x BB raise.

My AKs was against 66. I was almost 100% sure I was not against AA or KK here because of the action (and its 5-max and I have an Ace and King already).
