the residual aroma left in a bathroom after a woman has dressed for work, sprayed herself with perfume and then realizes she has to take a shit. When she exits the bathroom the remaining odor is a blend of poop and perfume. The result is "PooFume".
To attract members of the opposite sex, some women will finger their poontang and then rub the poonjuice on their neck or other body parts. It is believed that the pheromones in the poonjuice activate some sort of basal caveman instincts in the male's olfactory glands, thus making the woman more attractive or seemingly "irresistable" to the male.
I metsome bitch that smelled like tuna but she told me she had on poonfume.
