One direction

One direction is one of the best boy band ever they were formed on the 23rd of July 2010 on a tv show called the X factor. The band is formed by Harry Styles Niall Horan Liam Payne Louis Tomlinson and Zayn Malik. The band took a break in 2016 for 18 months but still haven’t come back. There fandom is called directioners and currently the boys have there own solo careers.

Person: one direction is never coming back together

Directioner: Say that again and I will slap you accross the far like Louis did to Niall
