Haydn is the nickname given to a failing ninja. However they still think they are as good as Chuck Norris, but they need to practice their roundhouse kicks. They often criticise other great ninja's and should learn to take a leaf out of Jackie Chan's book.
"I am the best ninja. You're a ninja n00b."
"Dude. Stop being such a Haydn."

the most amazing guy you will ever meet, the sort you only realize how much he means to you when he;s not there. A guy that makes you feel "ohh" so happy, and is quite funny too. He's always looks impeccable.

The guy every girl wants.

The guy every other guy wants to be.
Haydn's across the globe.
