LL Cool J stands for Living Legend. He is also the one who came up with GOAT fittingly enough.
At the 2021 Rock N Roll Hall of Fame inductee special in Cleveland, Ohio we got to here Dr. Dre share some other great stories about the New York rapping legend who is really true to his name:
At 17 he came out as a superstar for Def Jam and Dr. Dre was just geting started spinning Rock The Bells in the club where the audience went crazy, With 13 studio albums over a decade. From Around the Way Girl, Doing It, Going back to Cali, and its not where you're from it's where you're at as the legend says he lives in California now and Dr. Dre gives him some "California Love". While he stayed true to his roots in Queens New York the rare artist beloved by you, your mom, and how many other rap artists stay relevant after 30 years.
LL. Cool J is the one who came up with the phrase GOAT the Greatest of All Time. The Tom Brady's and Michael Jordans of the world are thankful for that!
Really though the LL stands for Ladies Love Cool James.
