1 - 5 twats who extremely piss off any guy whose girlfriend is a 'directioner' and makes their lives miserable while they talk about how hot Niall is or how 'cute' Zayn's eyes are and all the while make the guy seriously consider leaving.

2 - The one main flaw in a perfect girlfriend - they could be beautiful, funny, caring, and loving, which would make them perfect except they're a 'directioner', therefore dragging down their credibility.
1 - (girlfriend) omg I love One Direction and am going to see their film and Niall is the hottest creature ever and I'd almost definitely leave you if he came into my life

(boyfriend) (thinking: please fucking shut up, this is literally the last thing I want to hear, I wonder if she realises she's making me feel like shit)

2 - (person 1) Oh wow I'm jealous of your girlfriend, she's lovely and funny and insanely hot

(person 2) Yeah man I agree with you, she'd be perfect if it wasn't for the fact she's a huge directioner

(person 1) Oh shit, I feel your pain bro

A boy band which came in third on the X Factor in 2010, their fanbase consists of teen or pre-teen girls who care little about the music itself and merely wish to ogle the five boys as much as possible. These fans call themselves Directioners, not to be confused with Directionaters, and have become extremely possessive of the five boys in the band, despite the fact that these five people will never know of their existence. All of these fangirls will post variations of the definition of this boyband, most of which will include they words "hot" or "sexy", and won't really mention any music at all.
Directioner: I love One Direction, they are soooo hot! And sexy!

Sensible Person: What do their looks have to do with their music?...

Directioner: Does it matter? *stares at picture of boyband longingly* They are soooo hot! Their music is AWESOME! And they are sexy!

Sensible Person:Personally, i hate them.

Directioner: How dare you insult my future husband(s)! Their music is AWESOME and they are SO HOT!

Sensible Person: *realizes he/she is talking to a Directioner who will not see reason, presses on anyways* If they're so awesome, why don't they have any BOY fans?

Directioner: ...The're still hot.

Sensible Person: *sighs, walks away, and listens to iPod (Panic! at the Disco music) to wipe his/her mind of this awful discussion with crazed fangirl*

A band of closet(?) homosexual teens which was formed after they all met at an orgy and found out they could all moan in harmony when they simultaneously came in each other.

They are the reason the Apocalypse will be coming a few millenia earlier, owing to the legions of infuriated, sexually frustrated teens and pre-pubescent girls that will raze the Earth once a sextape of the band jerktape each other off goes viral.

Also, probably the only 'band' to have lip-synced at the Olympics.
Guy : Dude ! All the guys in your class were caught on tape at some gay orgy in an abandoned Prius with Dirty Mike and the boys !

Me : Looks like they've been One Directioned
