A girl that guys are dumb enough pay $20 for a 5 minute dry hump. She swoons at his ridiculous pickup lines and laughs at his stupid jokes to make him think he's getting somewhere with her, so he continues to fork out the money in hopes of impressing her to the point that he'll get more than just a case of blue balls and an experience to jack off to before going to bed that night. But after giving her the last of his money, she tells him she'll be right back. After several minutes he realizes she isn't coming back, so he leaves the club disappointed and flat broke, and as he's leaving, he sees her grindin her ass into some other dumb bastard's lap.
Chris Rock didn't do the song for his health, you know. It's a warning: "No matter what a stripper tells you, there's no sex in the champagne room."
