alternative for bum bag, a bag which one wears atop their buttocks, (secured by a belt-like device with a clip for attachment and detachment) while running, walking, etc.
in the television series, 'the nanny', yeta wears an 'arse sack' incorrectly, and wears it on the front, hence the name 'arse sack' or 'bum bag'
"hey, mum, have you got your arse sack on yet so we can get runnin'"

polite way of calling someone an idiot, jerk, stupid, or inappropriately mean or stupid without sinking down into the usage of obscenities. Taken from the term arse for backside or bum and the word fart the sound that comes out when a person passes gas. Basically telling someone their comments are full of hot air and just trite, mean or silly.
E: Look at that bird in the sky!

Guy2: Yep that Jenni she keeps on acting like an arse fart.
