there was no snap in his turtle

[thedaffodils]

Hi, The text I quoted is an excerpt of Friends, an American sitcom. What does 'there was no snap in his turtle' mean? Some Chinese say it means to have sex. I think so from the context. If it is true, why does it refer to sex? What are 'snap' and 'turtle'?

Thank you!

Frannie: Hey， Monica!
Monica: Hey Frannie， welcome back! How was Florida?
Frannie: You had sex， didn’t you?
Monica: How do you do that?
Frannie: Oh， I hate you， I’m pushing my Aunt Roz through Parrot Jungle and you’re having sex! So? Who?
Monica: You know Paul?
Frannie: Paul the Wine Guy? Oh yeah， I know Paul.
Monica: You mean you know Paul like I know Paul?
Frannie: Are you kidding? I take credit for Paul. Y’know before me， there was no snap in his turtle for two years.

Joey: (sitting on the arm of the couch)Of course it was a line!
Monica: Why?! Why? Why， why would anybody do something like that?
