A build up of vaginal fluids that forms a lining in the mouth after licking a girl's lady parts for a long period of time. This will only happen if you perform cunnilingus at night, and then neglect to brush your teeth before bed. Thus, resulting in you waking up the next morning with symptoms of Oral Vaginosis.
