arse fart

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!
A: There's no bird in the sky why are talking like an arse fart again?

Guy 1: Look at Jenni over there talking about Anna again and throwing salt.
Guy2: Yep that Jenni she keeps on acting like an arse fart.

fart higher than your arse 

To harbour an inflated opinion of oneself.

As in “That lad David Beckham. He farts higher than his own arse”.
