"Oh no you di’nt!" What's going on here?

I’ve always seen “Oh no you di’int” in response to an action the speaker is angry about: it’s a sort of mock-disbelief to emphasize the improper or impolite nature of the action in question.

“I saw Bill checking out your wife the other day—maybe he thinks he can slip one by you.”
“Oh no, he di’int!”

I don’t know where this originates, but I have found this http://www.phrases.org.uk/ from which the phrase can be searched.

I couldn’t find it in the Brit phrase site, but I did find it on the Urban Dictionary‘t.

I’m still looking for people’s understanding of the various nuances of this phrase. When would you use it? Has it been used on you? Why?

They say it comes from the ghetto. I wonder if it got popularized in a movie.

Here’s an example of dialogue I don’t get:

Shandice) ‘Mhmm suga I just got mama some bangin new lipgloss yall know what im say-en?’

Honey) ‘Mhmm honey that gloss aint poppin m-mm no way no how yall know what i mean girl’

Shandice)‘Oh no you di’ent!’

Honey) ‘M-mm thats righht suga-pie yall wouldnt know style if it slapped yall in that cheap orange pineapple yall call a face n yall know what im talkin bout mmHMmmmm’

From the Urban Dictionary

“oh no you didn’t” in this sense simply means “what? the audacity!” usually the result of saying this means it probably needed to happen. it can be an urgency or it can be factual.

It’s beyond an affectation, totally overused and grating.

@ daloon: “Oh stewardess – I speak Jive.”

Shandice) ‘Mhmm suga I just got mama some bangin new lipgloss yall know what im say-en?’
Hey, I just bought some new lip gloss. It’s really good.

Honey) ‘Mhmm honey that gloss aint poppin m-mm no way no how yall know what i mean girl’
Really? it doesn’t look so good to me.

Shandice)‘Oh no you di’ent!’
I can’t believe you just said that.

Honey) ‘M-mm thats righht suga-pie yall wouldnt know style if it slapped yall in that cheap orange pineapple yall call a face n yall know what im talkin bout mmHMmmmm’
Yes, I did just say that – and furthermore, you are ugly and have no style.

It is so annoying, precisely why I added it to the phrases to never be used again thread. @PupnTaco, I’m not sure when I’ve laughed that hard…thanks~

It came from Maury.

by the way, you are… NOT the father!

It came from a ghetto fat black woman in south central somewhere : D

It seems to imply incredulity. And sometimes it can be playful – said with a smile.
@Daloon, any particular reason why you asked? Did you hear it today?

And I loved PupnTaco’s breakdown.

Yeah, it’s incredulity, like “You didn’t just go there” or “I can’t believe you just said that.” Personally, I find it hilarious, but that’s just me. ;)

It’s a glottal stop

It’s like No Way! To which you’d reply Way!
