Because of Siblings

If you have siblings, you knows that they are everywhere in your life. You can't avoid them. You see them whether you want to or not; they're in the kitchen eating your cookies, hogging the bathroom in the morning, making a mess in the living room. But most of all, you here them, yelling "Mom Mom Mom" or "Dad Dad Dad" or "that's not fair. That's sexist. That's age-ist". Which means you also hear all the stupid things they say all the time.

So i ask you, what is the stupidest phrase you have publically repeated that your siblings said first? One if those ones where you go " I can't believe i just said that. That was such a ________ (insert sibling's name)"

Before I left for Jamaica, my mom and I were having a disagreement and I told her to "stop being an evil platypus".
