Babies in roblox who are very self absorbed, rude, and picky. Usually don't like other babies, unless they're "cute" and act like them. Are known for bossing around their mwa mwas for toys, mwa mwa milky, and other weird things. Commonly found in Adopt and Raise.
Roblox Player 1: Awh! Is that a baby? So cute!
Roblox Player 2: That's one of those roblox baby boos, don't adopt it.
