The prime definition of a sweet guy with a horrible choice in girls. A Gavin has the option to have someone that all the guys in town want and will usually be caught standing her up for a girl who doesn't even remotely compare. A Gavin has an amazing humor and doesn't give himself enough credit.
oh my god i can't believe he chose Jess over Kate!! ew what was he thinking, is he blind!? that guy is such a Gavin.
