Snooki & Letterman Fist Pump, Talk Sex (VIDEO)

Nicole 'Snooki' Polizzi sat down with David Letterman Tuesday night and taught him about the drinking, sex and fist pumping of the 'Jersey Shore.'

They start drinking vodka and Jagermeister about 8 o'clock, then go to the club to 'get it in.'

He asked her to describe the 'lot' of sexual activity he had witnessed. Snooki said of her male castmembers, 'Their mission when they go out to the club is to get it in and smoosh.'

Then they fist pumped.
