look up any word, like donkey punch:
 
1.
something i do too much of whilst msn-ing and emailing. it's a bad habit in some respects - kicks bloody arse in others.
Yay-ness (unnecessary hyphen)
msn-ing (as i did earlier totally by accident)
ill-ified (yet again)

basically the art of unnecessary hyphenating is to break down perfectly fine words or to totally invent your own. You can do this by taking the 'ing' off a word and adding a hyphen in the middle OR adding suffixs to the end of normal words. like yay for example. this can then become yay-ness (for more yay!) you can mix and match many words and suffixs - my three favorites are:

-ified
-ness
-ing

Have fun =)
