Is this a six pack?

I can't believe for all the talk about "six-pack this" and "six-pack that" on the internet there is no visual definition of what it is! All the pictures are of fitness models in competition form, which is hardly a worthwhile goal for 99% of the people out there.

My trainer's skin-fold test put me at 7.5%bf (which I don't really believe), 164lbs 5'9". This is a cold flex, first thing in the morning.

So what do you think, do I have a six pack? Ladies?
