Last season on The Jersey Shore, a man threw a punch at Nicole "Snooki" Polizzi.
This season? Just a drink.
The newly single MTV reality star, 22, was doing shots with Jenni "JWOWW" Farley, 23, at Ocean's 10 bar in Miami Saturday at 6 p.m. when a man approached her.

"She was in a good mood, but this particular guy was obviously interested and she wasn't,” witness Fred Hernandez told RadarOnline.com. "She told him, 'Don't f--- with me' so he snatched her drink and walked off."

The situation escalated from there.
"I guess he provoked her by wanting an apology and she flipped out," the witness said. Snooki threw a handful of food from her table at the guy, and then slapped him on his shoulder and his face -- before tossing a plastic cup at him.

The unknown guy retaliated by dumping his own drink all over Snooki. JWOWW ran over screaming "What the f--- happened?" as security threw him out.
Snooki said, "He took my drink!" After taking a few seconds to re-do her hair pouf, she continued partying with JWOWW -- as MTV cameras caught everything on tape.
Season 2 premieres July 29.
