Something only Kim Kibum (Key) from SHINee is.
(Word he included in one of his Instagram updates, that has now become legendary in the SHINee Worldfandom.)
"of course i'm practicing # of course he is ONEW # of course i'm jabiless"
This is the same as head or a blow job. It's the greatest way to tell human resources or your boss to suck it without them knowing what you're saying. Made famous by an old fella I know.
Hey (insert name) why don't you give me a jabidoo! What's that? A gold star for adults!
