Pronunciation: Bay-Bee BOOOOOOOOM!!!!
Function: Big Bang
1: The sound a baby makes when it explodes.
NOTE: No babies were harmed in the making of this HORRIBLE joke. I should also reiterate that one of the first rules taught in the best-selling child-rearing handbook "Dr. Spock's Baby and Child Care: 8th Edition" is to never, never, NEVER EXPLODE A BABY!!! Unless of course that baby is evil and all possessed by the devil and such. If that's the case, well then, I guess it's all right if it's for a good cause and all.
