Literally, an anagram for "well I'll beat a baby jew to death". A horribly offensive anagram that isn't meant to be taken literally. Commonly used as an exclamation of surprise. This was orginally derived from a racist joke/prank.
Bob: "I just won the lottery."
Mike: "No way. Let me see you ticket."
Bob: "See right here."
Mike: "Well I'll beat a baby jew to death (wibabjtd). You did win the lottery."
This is similar to "Well I'll be a monkey's uncle."
