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!!!
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 organiccousin but is purely technological.
The Phonefart includes iphones, blackberries, zack morris' telephone, any cellular device left on a table.
Boys who enjoy yaoi (a genre in Japan that contains sexual and/or romantic relations between two men); literally translates to "rotten boy"; corresponding female : fujoshi
