An exclamation yelled at the top of one's lungs while running through the house, arms flailing, air-drying your wet, naked body.
Natdrea, "Are you almost done in the shower, Phil?"
Running through the house naked, Phil, "Booooooooooooooooooooooo oooooooooooooooooooooooo ooooooooooooooooooooo ooooooooooooooooooooooooooooooooooo oooooooooooooooo ooooooooooooooooooo oooooooooo!!!!!!!!! !!!!!!!"
Natdrea, "Sounds like the shower is free"

A Boo is a small, fluffy round pink or white cloud-like creature. They are special unique things. They are usually quite almighty creatures and hold many powers. Special Boos have tiny wings and halos, representing and guarding the other not-so-special Boos. One thing about Boos, is they absolutely love Bears.
Boo: I love you, Bear
Bear: I love you, Boo.
