When something (usually children) is so awful and atrocious that when someone asks you if you have anything to do with it you blame it on Bebe's Kids.(or "someone else's problem")
Best used when denying something straight away to stay out of trouble.
1-"Did YOU make this movie?"
"Oh no way man...that's BEBE'S Kids."
2-"This turkey sucks! Did YOU make it?"
"What? Of course not! That's Bebe's Kids."
