I was listening to Tony^3 "If I Had No Loot", I realized on the chorus they sample Ice Cube rapping "And you can new jack SWING on my NUTS". Back in the day like 93 when the song came out I never knew WTF what said there nor that it was Cube being sampled.
Ahh, what a fine example of sneaking obscenities into a song that gets mad pop radio play. Prolly even today that song gets played on "best of the 90s & today" KS95-type stations
The only other example I can recall of this phenomenon is when Sugar Ray "I Just Wanna Fly" had Supercat on the chorus adlibbing some Jamaican-steez english which I'm not certain but I think included some n-bombs.
