"Daaaamn, that Gap Though" ... Ok ... and

Can someone explain this to me?

I've heard cacs and brothas alike utter this phrase when referring to a woman's thighs...
Supposedly, the notion is that a woman should be able to stand with her feet touching and her thighs should never touch.

I've never understood it...

The thicker women I have been with do not posses his coveted "gap"... You know ... because they have thick thighs.
Personally, I deem that a good thing, rather than a bad thing.

Am I missing something?
