Nialf 

A Nialf is the act of sticking one's penis inside their gay lovers anus, and bending over, between their legs to such their partners penis.

Travis went to brown town on Brandon last night man. I even heard that he nialf'd him!

niall in Japan 

Something directioners don't talk about. It took a while for me to understand what it was. So, basically, it's m a s t u r b a t i n g. To those of u who don't know what masturbating is, it's fucking yourself. So, yes, that's what Niall was supposedly doing ... in Japan.

harry: "so what were you doing last night?"

louis: "i was doing the niall in Japan"

harry: "oh..."

louis: "don't worry, i was thinking of you"
