living room chef 

This is a similar concept to backseat driving; this occurs when an individual shouts out questions or gives unsolicited advice to the cooking or baking process from an adjacent room. Extremely aggravating, hence the reason he or she is in the living room and not in the kitchen.

Mom (seated in a comfortable chair): "Did you remember to set the timer? I smell something burning."

Adult children (in the kitchen preparing a delicious meal for the family): "Quit being a living room chef; we got this."
