They may have had their share of romantic ups and downs on Jersey Shore's fifth season, but when push comes to shove, Roger Mathews will do anything it takes to protect girlfriend Jenni "JWoww" Farley.
On Thursday's episode of the MTV hit, Mathews is quick to defend his love when a seemingly intoxicated patron at Seaside Heights, N.J. club Karma gives her unwanted attention.
"This guy is non-stop grabbing me, pulling my dress down, and Roger's like 'back off,'" Farley says in the above preview clip before Mathews punches her tormentor in front of the Jersey Shore gang.
As the agitated clubgoer is escorted out by security, cast member Ronnie Ortiz-Magro puts the situation in perspective.
"At Karma, you can either walk out the door or be thrown out the door. You don't mess with Roger's girl," he says. "That's Karma for you…karma's a bitch."
Watch more of the explosive Karma altercation above before Jersey Shore airs at 10 p.m. (EST) Thursday on MTV.
