I know, I know
A sentence or phrase used by someone (usually a kid) who becomes utterly annoyed hearing the same thing over and over again and being told what to do (usually from their teacher or parents).
Mom: You need to do your homework young man and you need to get it done now. Son: I know, I know! What's what I'm trying to do, give me a break would ya? Mom: I can't tell. Do it now
