Noun, A term of endearment,toward a young child,usually African American.It's especially used in Baltimore, by single,unattached mothers to convey not only tender affections, but family status, upon the young infant,and preschool sons, who are their nearly constant companions.Origin of this definition may be from the Hannah Barberra cartoon,Yogi Bear, in which Yogi is befriended by his cute, but wise,little sidekick BooBoo, with whom he has a close, bumbling but kind,paternal relationship.
Ain't no gentlemen o' dis ho(u)se, but my Boo,Damone,is his Momma,s lil' man.

A scary ghost creature in the Mushroom Kingdom. Mario faces these a lot. These pearly-white ghosts will become invisible if anyone faces them. They usually cannot be disposed of. There are also other Boos, like the Big Boo, King Boo, and more.
"I thought I heard a Boo, but I turned around and saw nothing."
