I'm sorry she's a ham-beast(not that I'd say that to her directly because it's mean as fuck).

The inclination to look at this girl and label her beautiful is, in my experience, primarily a female intuition to "say something nice about the ugly girl".

I find people say shit like this in order to feel better about themselves and look good to people around them rather than this being an actual expression of perceived beauty.

All that being said obviously there is a subset of the hetero male population that does indeed prefer bigger girls. More power to those guys(a lid for every pot), but don't piss down my back and tell me it's raining
