niwt 

If you are friends with someone, and you are practicly twins, but you are not related. You have similar characteristics, appearances, and usually act the same. You are best friends.

We're so close, she is my niwt.

niwt 

You and someone else are very alike. You are almost like twins, except your not related. You're usually around the same age and have similar characteristics. If you wish to use the word plural, you just say sniwt. Pronounced:new-eat, and snew-eat. Also, twin backwords.

Oh my gosh, you are like my niwt!
