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”.

I never pay attention to rap anyway. To me it is crap, but thanks for researching it. The bottom line is, I think this will get worse before it gets better.
You have remember that songs can have double meanings.
It might just be a co-incidence that the song was written three years after it started.
