yiffniff

A paradoxal word. It is so because 'yiffniff' cannot actually be spelled, as it was read in the 2007 FCAT writing assessment. It is now referred as a transitive/intransitive verb, an adjective, adverb, an adverb describing a verb/adjective, a noun, or a general exclamation. It is also a great substitute for profanity such as 'fuck', since it is so versatile.

Yiffniff can be spelled (and has been tried to be spelled) as follows:

Yiffniff
Yyfgnif
Yhighnnigh
Yhyyfghfh
Yhhghnyyf
and so on and so forth.

Yeffince

The name of the famous explorer, 'Yeffince' originated when what was then the nameless void said the word 'Vince'. Schlimpy, King of the pixies misheard and mistook it for 'Yeffince'. Thus the nameless void became Yeffince, and Yeffince the nameless void. Often shortened to 'Yeffin' for general convenience.

"I say, Yeffince, just how many of my pancake daughters are you hiding under that donkey?"
