This has given me an idea for a new app and device called "The Pisser".
Incorporating advanced noise-activated technology, it will start recording once you scream "I'm really gonna take this pisser!"
Using an in-built accelerometer, the length and duration of your pisser will be recorded and cross referenced with the reading from the custom gas-chromatagraph which samples any rectal emissions during the pisser. Dividing the two figures gives a hero rating which can be displayed to all your followers using the The Pisser App.
Anyone interested in bunging me a hundred quid to get development off the ground?
