ain't 

Originally a non-slang word, ain't began as a contraction for "am not", as in "I ain't stupid." When people began to use it improperly as in "He ain't", which should have been "He isn't", people came to consider it improper use of language. Today, it's known to be used predominantly in the south and by uneducated people.

I ain't yo' momma.

He ain't goin' to eat those nasty baked beans.

Guy 1: No for real she does.
Guy 2: AIN'T even Smuckers.

You Ain't Got No Soap. 

Definition: 'you're full of it', 'whatever' or 'you're not that cool'. Soap is a valuable item in jail. Having a good bar of soap makes you a bit cooler, better/luckier than the rest of the inmates.

"I don't know why it's taking him so long to hang that new front door, damn, I would be finished already!"

His friend: " Oh you think you can hang doors now hu..? Psssh. Ha. You Ain't Got No Soap. "

Barnabas and Amy T

An extremely epic Christian rap group which originated in Seattle. Their iconic song "Head Down", a Calvary Chapel High School classic, has not only cured the depression of many lost souls (specifically those taking advanced classes in high school), but also the infamous Papa Wayne. They were totally 100% not obligated at all to perform at Calvary Chapel High School and other gigs. They are a married couple and have an epic gamer baby. As a high school kid Amy T did some ******* things which she would not approve of now (yes). Their music is 100% amazing and perhaps some of the greatest of all time.

Must have been a Barnabas and Amy T time
