code for: What's That Bitch Talking About?
What's That Bitch Talking About is a spoof game show featured on Saturday Night Live when Tina Fey hosted. The title can also double as a phrase used in conversation or in the classroom when an annoying person or teacher says something unbelievable and/or difficult to understand. It is said in code so the person being referred to as "bitch" is unaware and therefore not offended.
