In the song "Smooth Operator" by Sade, as a kid I heard....
"No need to ahhsk he's a smooth carburetor.."
I guess the word carburetor was probably heard from my dad who often talked about cars, fixing engines, etc. So I must've plugged the word into the song. I was probably 8 or 9 so what the hell would a smooth operator be? I learned the correct lyrics when I was older.
