That ain't it sis 

It's not fantastic. Not good, but close to good
For example someone stole BTS's beat for a song, and you say

Nah that ain't it sis.

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

Feri G in 2019: Let me sing the national anthem like a drunk aunt witch

No one in her entourage: Nah, this ain't it dog.
