how can i know that i m directioner ??

To be a directioner you have to support them no matter what.... Being a directioner doesn't mean you have to know everything about them or have all their merchandise

Just be a fan. As long as you support the boys you're a Directioner.

U start to feel like ur in loveee with them then u spend all ur time thinking about them then u loose ur old friends and get new directioner aka crazy friends because all your old friends think ur mental and finally u know everything about the boys

Be a big Fan and support them no matter what like they did good or bad for once if u want to be a Directioner.

When u constantly find yourself thinking about them. :D
