bum rush 

Similar to the expression "left holding the baby". i.e. you ask a group of friends or colleagues to volunteer or help in some way, and everyone actively avoids you. All you can see are "bums rushing away from you".

I asked my friends to help paint my new home, but all I got was a bum rush.

Bum Puff 

A bum puff is when you take either a PVC pipe, a toilet role, or any form of cylinder with an opening at each end. You place this cylinder partly into your ass, thus shitting through the pipe whilst playing the Thomas The Tank engine theme.

Bro I was really bored yesterday so I decided to bum puff for a bit

Bum Choppipng 

The practice of harvesting fingers or toes from homeless people for the purpose of defrauding a fast food outlet. Practitioners place the harvested digit into a serving of fast food and then claim that the restaurant is at fault.

Bored and pennyless, Jim and Danny resorted to a bum-chopping scheme to try and bring in some cash.
