Flapper Valve

While having anal sex and your penis goes too deep and hits the "flapper valve" causing your partner to shit the shaft.

Sarah told me yesterday that her and Bill had anla sex and he hit her flapper valve.

Shit the Shaft

When your partner shits on your penis as a outcome of anal sex or because of your fucked up idea of an kinky fantasy.

I let Anna Shit the Shaft to try and spice things up in the bed room.
