SomethingAwful users update Trout's Wikipedia page with the nickname. For citation, they use legitimate-looking links that don't actually reference the nickname (which, after all, hadn't existed before that day). The links fool Wikipedia's editors and buy Weed Mouse some time. Within days, journalists and bloggers start picking up the name and using it in their articles. SomethingAwful users quickly update the Wikipedia citations with real examples that prove the Millville Meteor is in active circulation. Two weeks later, Baseball-Reference.com updates its Mike Trout page. SportsCenter uses it on July 18.
Trout hears the nickname. "I don't know where they got that," he says. But later in the summer, on eBay, a baseball is being sold that Trout has inscribed with it, in silver ink.
