Phone Fart 

A phone fart is when you (or the person on the other line) accidentally hits one of the number keys on his/her phone, resulting in a jarring high pitched noise that assaults the ears of both parties.

I hung up on Ben after he phone farted like five times. My ears are ringing!!!

Phone-fart 

When your silent-mode phone vibrates on a hard surface and makes a loud buzzing sound, like flatulence.

I put my phone on silent for class, but still got in trouble after a phone-fart.

Phonefart 

Those times where you leave your cellular device on a table or hard surface and when left on vibrate rings making a brrrrrrt-brrrrrrrt-brrrrrt sound. Similar to it's organic cousin but is purely technological.

The Phonefart includes iphones, blackberries, zack morris' telephone, any cellular device left on a table.
