look up anything, like your first name:
1. NST
Similar to LOL but i realised that when i am at my computer i generally don't "Laugh Out Loud". I kind of snort air out my nose and move my head back a little at the same time. Hence the term "Nose Snort Thing" or "NST".
When Someone Tells a joke that isnt that funny and you have to make some sort of a response so you dont hurt their feelings. Thats when you do the NST.
2. NST
Acronym for No Shit Talking
Me: Omg..where is Regina Phalange's head lately? (NST intended)

Brit: I have no idea..but, I think she's doing it for attention (also NST)
3. NST
short for "north side of the tracks."
The NST of the rivshow is the best thing since groy.
