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!
Somebody who relentlessly tries to get out of doing anything work related unless it will give them a chance to kiss the boss's ass, or look like a real go-getter.
Until the boss showed up I thought he was in a fuckingcoma, now look at him. What an assweasel.
