You have just woken up after a shag, you need a piss and you also need to get rid of the used condom still on your cock, you also need to make certain that the condom is totally disposed of.........enter the POWER FISH, holding the condom still in place you empty your bladder into it, then precisely positioning yourself so that the baloon of piss is directly over the deepest part of the pan, then let go immediatly with both hands. A 'bonus power fish' is sometimes achieved whereby the payload drops with such force that it vanishes round the U bend immediately without even flushing.
The science behind a bonus power fish is still poorly understood but may have something to do with the shape of the particular pan and also the volume of piss in the skin willie. BPF's still only account for 5% of Power Fish.
Re-enters the room....<Thinks> Fucking dynamite Power Fish.
She <thinks> wierd cunt, sounded like a power dump, I wonder if his arse is prolapsed?
