Stupid "word" that shouldn't even be in the urban dictionary. Used most often by people that "think" they are with it. Supposed to mean, "great!", or short word for "fabulous"."Wow, you look absolutely faboo" but really if you even use the term "faboo" it just means you're totally uncool and weird.
Dude, your t-shirt is faboo!
