n. The resulting appearance of an obese woman's inner thighs when she is wearing a skirt and sitting.
Oh my god did you see her vagthighna when she sat down? It's like her actual vag lives in a gated community.

When a woman is wearing a skirt and her thighs come together to form the appearance of a vagina. Often, but not always, caused by excess thigh fat.
I thought I was looking at a sweet upskirt picture of Olivia Wilde but it turned out to just be a vagthighna.
