The hole of the booty. This phrase is like a non swearing version of "asshole." All of you should go out and call your teacher/principal/paid prositute/parent/gaurdian/sibling/pot dealer who always rips you off/your alarm clock in the morning etc. Booty Hoo is best said online in text in all caps with an exclamation point. Just like this: BOOTY HOO! Or in a plural like this: BOOTY HOOS!
