Get the Boo mug.
A small spherically shaped ghost that is only visable when your back is turned.
Mario tried to kill the boo, but every time he turned around to hit it, it vanished.

Get the Boo mug.
A term of endearment and affection used to identify your perfect counterpart. Your "boo" is extremely complementary to your own personality, and is always willing to take on any adventure with you, without hesitancy. Always there for you, one can never become sick of their "boo." Times together are a good time to be had by all, and times apart come with a significant void that can only be filled by 1 person - your boo.
Boo 1: Damn I miss my Boo.
Boo 2: Don't worry, we'll get some Boo to the Two time on again soon.
Boo 1: I hope so, I need everything I do to be fun again. As long as I'm with my Boo nothing can ever be lame.
