Shortened version of fabulous for those that are snooty and think their sh*t don't stink. It describes something that is really great, and well...fabulous!

A person of sheer perfection and fabulousness. Usually named Ryan, these "fabu" people are just so amazingly awesome that no other words can describe them. In rare occasions, some fabu people are named Lee-Anne...very rare occasions...
Wow! Ryan is soooo fabu.

A word meaning "face".
Originally used in a Bill Crosby stand-up segment about a trip to the dentist, where the suction tube affects your ability to speak properly, resulting in the word "face" becoming "fabus."

It has also been used in online gaming communities when talking about getting "headshots." e.g. I shot you in the fabus!
I shot you in the fabus.
There's something wrong with my fabus, it's slipping off my skull.
