Naughty By Nature scored their first big hit in 1991 with "O.P.P.," a hip-hop anthem that sampled the Jackson 5 and coined a phrase that became ubiquitous in pop culture. While the meaning of the last "P" may be open to interpretation, the song title was inspired by a drug dealer that lead rapper Treach knew growing up. "He said he was down with 'O.P.M.' --other people’s money," he said. "I started playing around with that, like, 'You keep the money, I’ll take the girl.' It turned from a joke into slang."
