The slang “5000” in rap and urban culture has a fascinating origin. It comes from the popular Audi 5000 of the 70s and 80s. Especially during the 80s, the Audi 5000 become one of the best-known cars all over the world. Later on, people would use the term as a means of saying “I’m going out” or “I’m leaving.” You might hear people use it like this:
“I’m 5000 because I still have work tomorrow.”
“I can’t 5000 right now I’m at a meeting.”
While it isn’t very popular nowadays, it has been cemented in urban culture, lingo, and rap songs.
