A combination of the words Piss and Vagina put together. A Pissgina is a vagina that has an unpleasant odor of piss and a small tinge of fish. A Pissgina is caused by the accumulation of piss inside the vagina that gives off a foul odor of disgusting piss. Or you can also joke about it saying things like Junior you have a Pissgina if the person smells like pee. (M or F)
Hey Junior close your legs I can smell your Pissgina from over here.
