There is a point at which exaggeration becomes ludicrous. Too much. Too far.
Unfortunately, within the furry fandom, where that point is varies from individual to individual. It is a very thick line, which is what she said.
Finding how far to exaggerate certain aspects of anatomy has always been a challenge for me. I like realistic anatomy, but if you do that you lose the hourglass figure or even visible musculature 90% of the time, which are both very fun. A little exaggeration is nice, a lot is silly, but sometimes silly is fun.
