Eminem, whose real name is Marshall Bruce Mathers III, began his music career in the early 1990s. He released his first independent album, "Infinite," in 1996. However, he gained significant mainstream attention with his major-label debut, "The Slim Shady LP," which was released in 1999.

This album, which featured hits like "My Name Is," launched into widespread fame and marked the beginning of his commercial success. The 51-year-old – also known by his darker alter-ego Slim Shady – is highly regarded for his complex rhyme schemes, wordplay, and ability to tell compelling stories through his music. Not to mention, he doesn’t shy away from controversial themes.

He has songs that address taboo topics like personal struggles, addiction, family issues, abuse, stalking and critiques of society. Eminem has won nine Grammy Awards and an Academy Award for Best Original Song for "Lose Yourself" from his movie "8 Mile." He is also one of the best-selling music artists of all time.

But despite releasing music for around 30 years, people are only just learning how Eminem got his rap name. One Reddit user asked: "Why did he call himself Eminem? Does anyone know why he called himself that? I have been listening to him for quite a long time but I never understood why he chose Eminem instead of something like Slim Shady." It turns out his rap name Eminem dates back to his childhood when he and his high school friend, Mike Ruby, adopted the names Manix and M&M.

The name M&M, short for M.
