A pejorative term used to imply someone enjoys sticking their fingers up someone else's anus, most commonly used as a gay slur. The name comes from pin tumbler locks as you need to stick a key or pick into the lock to move the pins to open the lock. The finger would be the key and the ass is the lock.

This term refers to when Bums, or homeless people, hide the money they have begged that day up their asses so the other Bums won’t steal it when they are passed out drunk.

A deviation of the Pokey Bum-Wank where a chocolate sweet is used as a replacement for the finger. The sweet treat is inserted into the anus whilst carrying out the five-knuckle-shuffle to heighten the participants' pleasure. This may also be of benefit to those that have to take emergency action to control their blood-sugar levels due to a diabetic emergency - though there is little medical evidence to prove that this will successfully prevent the patient from slipping into a coma mid-wank.
I am feeling particularly horny having left the gym all pumped up and after observing the lycra-clad lovelies that were also working out. However, I have unsuccessfully kept control of my blood-sugars and need to take urgent action. I think I will kill two birds with one stone and have myself a Flakey Bum-Wank.

Just relaxing, associated with homeless people with not much to do. A bit like a beach bum, hanging around in and out of bars.
I read the quote in a Jack Kerouac book, 'Piers Of The Homeless Night' 'And since I'm well and on the bum again & ain't got nothing else to do, but roam, long-faced, the real America....' and thought I'd check if there was a meaning on here but now I've read the section again I get what it means even more!

'Hey man, how's your day been?'
'well since I lost my job, I haven't had much to do. Been on the bum a lot'
