Since Jeff's friends have coupled up, he's become the fifth wheel. Scratch that. He's become the crappy spare tire that no one remembers is in the trunk of the car. He's tired of being ignored by his beloved friends, and he's determined to rekindle the good times, even if it means kidnapping them and forcing them to enjoy his dinner party.

When freeloader Phil is tossed out by the love of his life, Jen, he stays with two old friends who come upon a magic shirt that guarantees them sex with all the women they can handle. The three losers have their lives upended as Phil's friends pursue a daily diet of Maxim models and close encounters with Hollywood's hottest-but Phil schemes to use the shirt to win back Jen. And when an insane marine steals the shirt and threatens to use it on Jen, Phil's battle for her affections takes on dangerously high stakes. Chick Magnet makes it clear that the laws of attraction were made to be broken.
