Azizi,

I'm not sure the "double negative" "I didn't buy no ____" is only part of AAVE. I was raised in a predominantly white area (less than 4% African-Americans) and educated in segregated schools (I was born in 1946) until the ninth grade of high school. Yet, I remember being drilled in avoiding double negatives. I believe I and my classmates were quite apt to use double negatives like "I didn't buy no...".

I remember Bazooka Bubble Gum, but I do not remember the song or the manufacturer's advertising.
