LLN 

A abbreviation for the phrase 'laugh like Niall'.
Originated because of the adorable laugh of Mr Horan, only Irish member of the British/Irish boyband, One Direction.
'lol' was becoming too frequent in the 1D Family so Directioners now use the phrase lln instead.

*gif of the boys and Paul dancing*

Directioner 1: HAHAHAHAH A++++++
Directioner 2: IKR, LLN!!!!

LNN can also mean LAUGH LIKE NIALL if you're a Directioner.
So,if you see this word on One Direction pics it probably means that.

Another person: HAHAHAH. ;DD LLN!

LLN 

Laugh Like Niall. Niall as in the hot blonde from the sexy homosexual band One Direction. Niall is known for his amazing laugh, so some directioners say LLN instead of LOL.

Zoe: Louis just kissed Harry's face onstage!

Other Directioner: LLN! I love that homo!
