While on playground duty (yep…this is a 6-12 school, and all of the students have recess) I overheard a student say the following:
“I’se doin’ it right now, ain’t nobody not said nothin’ ’bout none dat yet”.
Now, let’s break down that beast of a quintuple negative:
I is doing it right now, is not nobody not said nothing about none of that yet
So, not and nobody cancel out, the second not and nothing cancel out…what the student was trying to say was, in fact:
I am doing it right now, no one has said anything about it to this point.
Ah, clearly spoken English.
