NATSA 

stands for (you're) "not allowed to say anything"

The girlfriend picks a bad movie to go see, but you're NATSA (if you know what's good for you). Basically used in situations where you just have to bite your lip and keep your mouth shut: old people taking forever at the checkout, people in wheelchairs bumping into you, people inviting themselves into your activities, someone's kids spilling juice on your new carpet, etc.

nasal-ingressive voiceless velar trill 

Linguistics joke. There's a fake IPA symbol to go with it, that looks like a pig snout.

It's linguistically correct description of, well, the sound pigs make.

First-year linguistics students can be humiliated by asking them to include nasal-ingressive voiceless velar trill in their presentation of rare and difficult-to-pronounce sounds in the West African languages.

nasal demons 

Recognized shorthand on the Usenet group comp.std.c for any unexpected behavior of a C compiler on encountering an undefined construct. During a discussion on that group in early 1992, a regular remarked "When the compiler encounters a given undefined construct it is legal for it to make demons fly out of your nose" (the implication is that the compiler may choose any arbitrarily bizarre way to interpret the code without violating the ANSI C standard). Someone else followed up with a reference to "nasal demons", which quickly became established. (see Jargon)

Your program has nasal demons.

Israeli Nasal Slapper 

When your best friend is passed out, and you get his girl friend to do a bridge over top of him with her ass above his head. You then plough her over top of your best friend with your sagging nutsack slapping his nose.

drew: "yo look, brandon passed out on the kitchen floor"
riley: "key, let's get sarah and give him an israeli nasal slapper!"

Naisargi 

Naisargi literally means Goddess of nature. She is not only the goddess of nature but she is also the goddess of love. She is someone who exactly defines what true love is. By nature she is extremely friendly and can mingle with anybody. At heart she is extremely beautiful. She is a 2 year old baby when it comes to behavior but when it comes to caring and loving she is even more than a mother. She understands the importance of relations and very well knows how to maintain them. She perfectly knows what it means to be in love and there is no other person who can love as she does. She is the best person on earth I've ever met.

I love Naisargi.
