Nikatchu

Nikatchu (noun): is a cross between a furry, little Indian girl and a Pokemon.

Nikatchus (plural) originate from a mystical place in North London known as Buntok.

Typically, a Nikatchu is vegetarian for the first 23 years of its life. At the age of 23, it then transforms into a Carnivorous beast.

A Nikatchu has special powers including apple belches, playing garba at high altitudes and singing well known pop songs without hitting any of the correct notes.

Nikatchus are surprisingly smarter than they look. They can also be highly dangerous.

Aw look!.... It's a Nikatchu!

Niatch 

A random insult, perhaps born when someone misspelled biatch but still thought it sounded cool. Is still catchartic to the word user, but doesn't have the same degree of offense as the stem word.

or
A mix of biatch and the n-word, and in that case, the word user should really rethink their word choices unless used ironiclly

"Mathilde, you're being such a niatch today, are you okay?"
