a fine ass, comprable to an ass, smelling of fudge, pseudo pretty, well dressed, and last but not least "the term used to describe them fine bitches and ho's"

I have never seen anything more asstastic than when Patsy from Ab Fab lit her cigarette with the London 2012 Olympic torch.

It just means awesome. Because asses are awesome. Similar to words "sick" or "wicked". And VERY similar to the expression "that's tits".
