Bum stink can be used in many different ways. The reverse of the words "stink bum" to "bum stink" makes the use of the phrase a little more amusing.
"I am going to the toilet to do a Bum Stink" - Meaning "I am going to the toilet to do a shit"

Or

"Have you done a bum stink?" - Meaning "Have you been for a shit?" or Have you farted?

It can also be used to tell someone that they have a smelly bum: -

"You have a really smelly Bum Stink" or "You have a really stinky Bum Stink".

You are a "stink bum". Also good when used in conjunction with "Poo Face", for example as a greeting - "Hello, Stink Bum Poo Face".
