This insult can commonly be found when and angel holding a Molotov cocktail of holy fire
"Hey assbutt!"
*throws molotov cocktail at Michael*

Bobby: "Can we not talk about this right now? In case you haven't noticed, we are literally in the middle of the APOCALYPSE? Idjits."
First used by the character Castiel ( Misha Collins) the word originated from the show Supernatural. To be used as an insult and to get some ones attention. Very useful when dealing with superwholocks.
I.e."HEY!ASSBUTT" as you throw a bottle of holy fire at them to send them back to heaven/hell.
An all-purpose term used to refer to a person who is irritating or otherwise. It is more colorful than traditional names, and is generally less offensive, so it is often used teasingly.
