The most common remedy for a flapho is a logjam, though it has only temporary effects. A logjam is also known as a blowjob.
The girl I wanted out with last night was a real flapho, the only time she shut the hell up was when i logjammed her. I wish that logjam had more of an effect though, because soon after the logjam she went right back to her flapho self, yammering away.
The act of sticking one's thumb between somebody else's butt cheeks and announcing "Log Jam!". This is not a sexual act, it is performed externally while the recipient is wearing pants. Best performed in front of other people.
Nick, standing behind Frank waiting in line at the cafeteria, jams his thumb up between Frank's butt cheeks and yells "Log jam!"
