Listen up, buttercup. The joke here is that Gina turns being called a "whore" because people hit her ass into an opportunity for more of the same. Basically, she's saying, "You wanna hit it too?" It's blue-humor because it's sexually suggestive. And you're not too bright, so I had to spell it out for you.
