What's Beef?

Beef is misspelling your own team's name to throw shade on a regional rival.

By now, it's been pretty widely publicized that the Nats sent two of their own onto the field this weekend in jerseys that read "Natinals." There are any number of explanations, most of which involve incompetence or ineptness, but theory I choose to subscribe to is this: In the 34 years between the Senators and Nationals playing baseball in DC, many in the capital region became fans of the Baltimore Orioles, the next closest team. The two are now rivals, if not on the field, then certainly for attention of fans and media. What better way to make a subtle anti-Baltimore baseball stab than to leave out the O's?
