look up any word, like ethered:
 
1.
The term that describes a fart that works similar to that of a suppressed firearm from Call of Duty. It is executed by shuffling the anus cheeks so they are wide apart then releasing the gas. There is no noise involved and leaves the farts-man conspicuous surrounding victims.
"A young schoolgirl was killed as a result of a silenced fart. Nobody knows who the murderer is"

"Hey are you playing Call of Duty?"
"No I did a silenced fart"
