noun
1 - The union of a
human ass and a toilet, which upon flatulence produces a low-pitched sound (bass) often heard in the presents of a
random jackass having a telephone conversation whilst shitting.
Over phone: What was that
sound? Was it an Asswoofer? Dude are you talking to me on the
shitter, in a public restroom? You
ass!
mumbling Asswoofer: Hehehehe.
