A bong is a smoking device that cools and filters the smoke before it’s inhaled. It is one of the most popular ways to smoke weed.
We use the word "bong" to refer to a device used to smoke substances from the water pipe. The word "bong" comes from the Thai word "baung,” which means a cylindrical wooden tube, pipe, or container cut from bamboo, and especially a large bamboo tube used as a fishing net.
