Hibou's are half-owl, half-human and are pure myth, or so most people think. Hibou's have the ability to summon owl's and shoot owl's out of their armpits and hands. They also shoot their droppings at people and their favourite food is rat. Hibou's diguse themselves as music teachers and will kill you if you don't listen.
Hao gave Mrs. Heroux the finger during music class so she transformed into a hibou and shot owls at him.

Get the crank dat hibou mug.
A name given to a friend who is skinny fat - meaning skinny, but eats a lot of junk food all the time but is still somehow skinny. These people also tend to have very large eyes, hence the hibou (owl) part (They usually grow their bangs really long to hide them though).

These people usually have wild mood swings and may seem to disappear suddenly around 7pm on certain nights to secretly go to their AA meetings. These kinds of people also usually have a pepto bismol in handy in case of nausea, heartburn, indigestion, upset stomach and/or diarrhea! (Especially at Amusement Parks and hectic rides like the Thunder Run)
These people are also lanky.
