Zuckerfish noun

A new subspecies of bloggers, tweeters, phone-pic snappers, and even newspaper pet columnists spawned by local sightings of Mark Zuckerberg, Facebook cofounder and boyish billionaire.

Zuckerberg acquired an Oregon-bred dog this winter; rumors suggested he had purchased a Portland condo. In a sentence: “These days, every time a baby-faced guy in a hoodie walks into Stumptown, a whole school of Zuckerfish surrounds him.” See also: the citywide Benicio del Toro crisis of 2001.
