When an obese person wears short shorts or a miniskirt and the rolls of fat on his/her thighs resemble a vagina. (Typically, however, the thighs are indistinct, as the person in question usually has thankles.)
A: I was at KFC this afternoon and saw some serious thighgina. I saw a woman with not 1, but 2, thighginas. Seriously.

B: I don't know whether or not to be impressed or cry. That's sick. Her thighs must have been ginormous.
