SwaG is swamp vag, as in swamp vagina, akin to swamp ass or
swass. Otherwise known as a horrible vaginal odor. Unlike swag (
swagger, free stuff, etc), SwaG is pronounced with a hard
G (as in gentle).
After an
afternoon of running errands and hitting the gym, my morbidly
obese girlfriend developed some serious swaG, but that didn't stop me from gobbling on her
moist stink-muffin.
