look up any word, like ratchet:
A furry critter (usually small like a rat, a gerbil, a hamster, etc., but larger animals like cats can also be fuzzbombs) that one has as a pet; esp. a pet that an individual has become highly attached to.
{Craig}: Nikki! Here kitty kitty kitty! Here Nikki! Come here, my special little fuzzbomb! That's a good girl!!!
