fin

A fin bong (a finish bong) is a way of smoking marijuana mostly known in the eastern and central europe. A "fin" is made out of a plastic bottle where the user would burn a little hole into the bottle and place marijuana into a bowl (tin foil, 13mm socket). Then the user would "cook" the fin with letting the hole go therefore letting water pour out of the bottle while simoultaneously burning the bowl and letting the smoke go inside of the bottle. After burning the marijuana the user would get the bowl out and shake the bottle for cooling and evening the smoke and then smoking it on usually one or two hits.

I want to get wasted, please cook me a fin.

Screw rolling, I'm gonna smoke a fin instead.
