This ain't it dog

Used to bring a person back to reality about a recent terrible decision they have made. The person is often embarrassing or humiliating themselves and are completely unaware of how they are perceived. Dog is used in an affectionate but slightly condescending way to endear the person to trust the judgment of the speaker. Pairs nicely wit the No One: Not a soul: meme format
