because is why

cliché I do not need to give you any further explanation or reasoning for my decision. Used especially as a retort to children in order to end an argument over something. A: "I don't want to go to bed! The sun is still shining!" B: "Too bad, it's your bedtime." B: "But why do I have to go to sleep if the sun is still out?" A: "Because is why!" A: "Why do I have to wear a coat, Mom? I'm not even cold!" B: "Because is why! Just do it, we're gonna be late!" I got sick of having to explain the thought process behind every little decision to my kids. Now, when they question me, I just say, "Because is why!"
