An acronym for "Puffy Upper Vagina." A condition which occurs primarily in older and/or overweight women, but can also be seen in men. This is when fat appears to be stored in the lower abdominal region rather than in the stomach area. Most often accentuated by high-waisted jeans, in which the PUV area is showcased like a giant fat bubble under the tight waistband. Can also be caused by "that time of the month"-related bloating. See also FUPA.
"Damn, did you see her PUV? She looks like my grandmother!"
"Man, I'm so bloated. I've got some serious PUV going on today."
