nisini 

Nisini is playful, sometimes silly and is always there for her friends. She's sometimes lazy, but when she's active, she could run forever!

Nisini is full of energy today!
"She's doing a Nisini."

Niesin

The female child of your bruncle/aunster. Your bruncle and/or aunster is your aunt/uncle and sibling at the same time, so their children, in this case the female, is your niesin; your sibling's daughter being your niece, and your aunt/uncle's daughter being your cousin. Therefore the end result is biologically your niesin.

My niesin Sally is such a cutie pie, she's my niece and my cousin at the same time.

nissin 

Extremely cheap (30p) but surprisingly tasty japanese noodles, far superior to any other cheapo noodles such as Doll, Supernoodles etc.

To everyone's surprise, these actually taste like the pork, chicken, or whatever it says on the packet, just don't read the ingredients!

I've been broke for a while so I'm living on Nissin noodles
