For the third season of Jersey Shore, which premieres tonight on MTV, the cast has migrated back to its natural habitat, Seaside Heights. With their return, we couldn't help but reminisce on the hard-partying crew's first season, when we started to learn exactly what "JWoww" meant. A couple of seasons and a few photoshoots later, we've come to a conclusion about the nickname's precise definition: "wow" is the only word suitable to explain her smokin' hot bikini snapshots. Reacquaint yourself with Miss Jenni Farley by clicking through the swimsuit (and pseudo-swimsuit) pics that put the much-needed extra "W" in "JWoww."
