Define What Do You Think You're Doing Meaning

What Do You Think You're Doing
universal parent language for stop. referenced all the time, such as in a netflix special of the comedian john mulaney. suprised nobody has defined this yet.

sometimes, our parents would ask us "what do you think you're doing?"
but that just meant stop.
they didnt expect you to just say
"well im smashing these eggs with a bottle rocket, you know because im so horny and angry all the time, and i have no outlet for it all, so... eggs."
(not a direct quote)
