1) Ninky nonk is a character from the greatest fucking show of all time (In the night garden).

2) It's a funny way to insult someone without the use of vulgar language
1) Ninky Nonk is like the best character ever
2) Lad 1: You sir are a Ninky Nonk

Lad 2: Well... um... your mum gay *Runs away crying realising he's a fucking failure who got destroyed by an innocent insult*

One of the most offensive insults known to man. If you call anybody a ninky-nonk they'll never forgive you and you'll have to get a new friend, use this new word wisely or you could turn your life upside down.
Dallan: That's it! I've lost it with you, you Ninky-Nonk!
Joe: *starts crying*
