Bum crumble

Bum crumble
A vigorous post-movement wipe following a particularly high-liquid content when coupled with cheap toilet paper peppered the seat with a light dusting of bum crumble - Alex aghast made his exit from the stall and returned to his desk, feeling still the warming reverberations on his cleftal horizon as a gentle reminder of his overzealous wiping.

moroccan bum wank

Moroccan bum wank, or MBW for short.

The receiving individual is restrained on the floor by as many friends/colleagues as required.

The person issuing the MBW is naked from the waist down and parades to the crowd/ audience for a few seconds to music( such as the rocky theme tune).
Then, the issuing party squats over the face of the lucky individual so that their nose is in the crack of the bum cheeks, then the issuer sciffs back and forward !!

Job done!
Dill was late for parade, so pipes gave him a Moroccan bum wank
