niss

the biggest compliment someone can be given. Few ppl are truly niss, however when someone is, everyone around them knows it and knows that he/she is the don. They must acknowledge his nissness.

Niss

A kiss on the neck. It is like making out with someone's neck region, but not touching their lips.

"Mark didn't kiss me last night, but he gave me a little niss."

Niss

Niss is everything. Instead of saying "She's tangled up in a bunch of yarn!" you could say, "She's tangled up in a bunch of Niss!" Usually it is used in place of a noun that you can't think of, or you can't explain. May also use nissyfoofoo as a plural form, just for a special thing, or as an exclamation.

That Niss is on fire!
Nissyfoofoo!
