naider
A naider is a water bottle with two holes in the bottom one just right for shoving a blunt roach in and pulling it through like a fat slug, the other hole is for blowing smoke out so you can keep puffing without choking on your own stink.
My naider saved my life after I inhaled a whole blunt.
I tried to use a soda bottle and it just exploded like a f***ing volcano.
My friend's naider is so old it's got more holes than a cheese grater.
