Gnar pow is when a region gets completely shit on with a snow storm. We combine the words Gnarly and Powder. Gnarly meaning over the top and extreme with powder, which is high amounts of fallen snow.
"Holy crap look at the gnar pow! I can't wait to shred!"
A person you hate intensely not because they deserve such hatred but because they serve as a focus for your general hatred. A healthy way to dispense with excess animosity.
Jake's not really that big an asshole. He just serves as my hate sink.
