What is a Hobknocker?

Well, tbh i'm no overly sure what the meaning of a hobknocker is, but if you've watched icarly you may have heard the the word being used.

I've searched the net and found numerous versions of what the hobknocker definition could be...

• It could be some one who is cool but is also a nerd! (Not sure how that works?!)
• Someone who likes to go around hitting people in the private parts. (Nice!)
• Or its a large hairy man or woman that like to go around molesting small animals in he or hers spare time! (WTF!)

Like i said i'm not sure of the actual answer is but a large hairy man or women molesting small animals, that has got to be the weirdest thing ever!?
