A spokesperson at the police department explains, "A summons means she'll get a court date, but doesn't have to pay bail to get out of jail. She'll pay a fine when assessed [by a judge]."

Jenni "J-Woww" Farley wrote on Twitter Friday, "Going to bail @Sn00ki out of jail... The things I do for this girl, I swear." Several "Jersey Shore" cast members where photographed visiting the jail.

When asked about Snooki's attitude while arrested, the spokesperson told Us, "The disorderly conduct charge pretty much explains it."

TMZ.com has footage of a wobbly Snooki falling off a bike moments before getting cuffed.
