A word from Norse lore referring to an exceptionally vile, despicable person - a person completely without honour. Examples include murderers and oathbreakers. NOTE: "Nithing" is NOT a misspelling of "nothing." It's a totally different word. It's more likely to be used by Heathens (neoPagan followers of the Norse Gods and Goddesses) than by other groups, but it has been seen elsewhere.
I don't know why those nithings expect anyone to fall for their lies anymore, we all know they couldn't tell the truth if their lives depended on it.
To get yourself high by squatting low, breathing in and out deeply and quickly for about 30 seconds, and then standing up as fast as you can and blowing onto your thumb without letting any air out for about 15 seconds. Most of the time it knocks you out and you wake up feeling like you're in Inception. Sometimes it just gets you really, really high for a minute or two. Do not try this at home when your parents are there!
Dude, are you ok? You just passed out!
--Yeah man I was natching try it it's fun.
