look up any word, like darude - sandstorm:
 
1.
Word for marijuana commonly used by my pal jake. To shred the gnar is to either put the horns up and shake em up and down or smoke the green ganja.
"Man check out this fucking dank ass gnar i got from richard!"
"Dude, what the fuck! Is that white widow man? Hell yeah let's go shred some gnar bra."
"the gnar is godly."
