look up any word, like thot:
 
1.
A body, typically female, that is curvy and thick in a pleasant way, but not at all concidered fat.
That girl is very voloptuous.

2.
Vague female term used by fat people to avoid having to call themselves fat, it's an indicator of insecurity. You may also run into this term when conversing with a person with a sexual preference for fat women. In both cases they will be highly insecure about it but also lack the resolve to actually do something about their unhealthy apetite.
F) You think I'm pretty, right?!
M) Y-Yeah, you're... voloptuous.
