Leave it to Jay-Z and Kanye West to boggle our minds with their play on words, but alas, they have done it again with their hit single "Ni**as in Paris."

The term "Cray" isn't a shortened form of "crazy," and it's not spelled "cray," it's actually "Kray." The reference is made to schizophrenic twins Ronald and Reginald Kray, who were the crime lords of London in the 50's and 60's.

The police were unable to find them on several locations, which would explain the lyrics "ball so hard muthafu**as wanna fine me. That sh*t Kray. That sh*t Kray. That sh*t Kray."

This concludes your lesson in rap history for the day.
