You can tell a lot about a year by its celebrity feuds. Taylor Swift's 2014 spats, for instance, solidified her status as the biggest pop star of the moment while those who crossed her came off looking like also-ran's. With the exception of one major conflagration in an elevator, the majority of this year's biggest confrontations went down on Twitter, thereby challenging whether or not they actually even count as confrontations. Most importantly though, thanks to social media's full takeover of our waking lives, any small slight could explode into a full-blown throwdown in seconds.
