It's 2012, and we do not yet know the pain that is the breakup of One Direction. We do, however, know about the absurd, semi-legitimate media-backed rivalry between boy bands 1D and the Wanted.
The two bands had never really gotten along, most likely because they were constantly pitted against each other in interviews — but also occasionally because they loved hurling insults at each other. What characterizes this particular feud is a general sense of chaotic mess, mostly begun by the Wanted — something they themselves admitted.
According to tabloid reporting, there were insults and shadiness thrown about here and there, with the Wanted's Max George likening 1D to the "new Jonas Brothers" and Tom Parker jokingly suggesting that they should settle the conflict once and for all in a boxing match. (And about 500 other digs that I cannot even begin to summarize and put in chronological order without becoming the Pepe Silvia meme from It's Always Sunny in Philadelphia.)
Now, back to this particular section of the overarching feud. It all began pretty innocently (and randomly) on Twitter, when Zayn called Max a "geek" for posting a picture of himself with Usher. (As an aside, if being a geek is what gets me a photo with Usher, I am 1,000% a geek and would like to be branded as such.) After the not-so-diss, Max poked fun at the name-calling, using the hashtag #GeekAndProud, and posted another pic of himself, but this time with "Gangnam Style" singer Psy (yes, I am throwing you back, indeed). In response, Zayn wrote that the "first step is total acceptance" and called him a "wannabe." From there, Max retorted, "That's not very nice, I was just starting to like you and your R&B songs, too." And, apparently, that was the straw that broke the camel's back as more of both groups' members chimed in, like Louis Tomlinson and Tom.
