This ain’t it 

When a person think what they did was funny or cute but in reality it was a fucking mess

Girl with bad hair: “yea my hair real cute right”

Other girl: “This ain’t it sis”

He Ain't True 

Not what he appears to be; usually a man who doesn't appear to be tough but is really a major badass

Remember what I said, Dude, watch your ass cause he ain't true.

You ain't shit 

= You're nothing.
However, 'you ain't shit' isn't necessarily an insult. You can comfort someone by saying that they are not shit.
You ain't shit vs. You are shit is definitely not the same. 'Ain't' is a general negation vernacular term.

FuckBoy : I cheated on my girlfriend and I don't even feel guilty haha
GoodMan : Really? You ain't shit, dude! (insult)

well ain’t that a kick in the head 

When something happens that is surprising, or something that makes you reassure or realize something.

Jerald: hey, did you hear that Jim broke up with terry for a nice looking bagel?
John: well ain’t that a kick in the head!
