Boo is a hamster who serves as the animal companion of the berserk ranger Minsc from the Baldur's Gate series of computer games. Minsc claims Boo is a miniature giant space hamster.

Minsc will lead with blade and boot! Boo will take care of the details.

boo

A pet name created by those who are entirely devoid of describing their true feelings for their significant other.

In other words? A "loving" term thought up by lazy, inconsiderate imbeciles.

"Oh, like, I SOOOOOO love you, Boo!"
