look up any word, like cunt:
 
1.
Nyarf... pronounced "Nee-arf"... an annoying little shit who just won't leave you alone, even if you reach your wits end and punch them in the thigh.

Ranging from poking you in the ribs whenever you're looking away, to dipping their cock in your pint when you're at the toilet then telling you after you've taken a few sips.

Some children can be Nyarfs too... usually a spoiled Niece or Nephew, or a friend's kid, who refuses to take the hint that you really don't want to sit and watch them fail their "epic stunt" on the fucking trampoline.
Nyarf: Watch watch, this is awesome... watch watch!
You: I'm busy! Go bother your Mum.
Nyarf: Watch watch, this is awesome... watch watch!
You: I'll watch later!
Nyarf: Watch watch, this is awesome... watch watch!
You: Christ. You're such a Nyarf.
Nyarf: But look, just look! Hey, are you watching? Watch!
You: *Sigh* fuh-fuck's sake
