The Kari Byron effect refers to a girl who is cute, but not that cute. Her cuteness is largely due to her being the only chick around a bunch of dudes (Adam, Jamie, Tori, and Grant), and especially if she does stuff that pale friendless virgins find hot, such as welding or shooting.
The chick I met at ComiCon wasn't that hot, it was just the Kari Byron Effect.
