Derived from "boo boo," a super boo is an especially wonderful. In particular, two cute kitties that can be considered super boos would be George and Grif. Certain humans are also super boos, but there are only two known examples today, one being the 23-year old future president of the United States.
I wish I could snuggle a super boo.
