Interesting. I did not know it went that far back. But then again, I think whites have been getting killed for a long time. Maybe it is just the name it is called, that has only been around for that amount of time.
That song is not about the knockout “game”. Good grief.
“Mama Said Knock You Out” is a number-one hit single by LL Cool J from his album of the same name. The song famously begins with the line “Don’t call it a comeback/I’ve been here for years.” Before “Mama Said Knock You Out” was released, many people felt that LL Cool J’s career was waning; his grandmother, who still believed in his talent, told him to “knock out” all his critics...
LL Cool J said in his autobiography that the idea for the song came from a discussion with his grandmother. He had said to his grandmother that he felt that he couldn’t survive as a rapper now that gangsta rap was popular and he was being dissed by several up-and-coming rappers. She responded, “Oh baby, just knock them out!”[3] At the end of the video, his grandmother says “Todd! Todd! Get upstairs and take out that garbage”.
