The act, or skill, of getting a common house fly to land on the tip of the penis. The subtle movements caused by it's tiny legs have been known to bring on ejaculation.

You can also try and coax the fly inside the penis, for inner shaft stimulation.

NB: Never try with a wasp.
Carl: Have you ever tried penal fly mate?
Rick: Yea, I tried it post anal as I had a few noticeable poo nuggets on my bell, small sure, but they were there. I Laid there for an hour, nothing. By this time i was soft and stank of shit so I had a shower.
