That. Like the one dragon from Kobayashi (Quetzlqatl I think?), if they're already thick, awesome, draw them thick. But like here, Bocci already had big boobs, but she's not stretching her clothes to ruination like in this image.

I feel like 'thick' has become, over time, just a poor, socially acceptable form of saying 'fat' now, instead of how it started meaning 'casual, non-fit sexy'.
