The other categories are just ways to misrepresent yourself. 'A few extra pounds' means fat, 'chubby' means obese, and 'curvy' means morbidly obese. Unfortunately, this is true well over half the time on POF, Okcupid, and Tinder.
The women who misrepresent themselves ruined it for the girls who actually have 'a few extra pounds'. I wont take the chance anymore
