A gravity bong. Easily made using a two litre bottle and a bucket filled with water. You put a bowl in the top of the bottle and cut off the bottom of the two litre bottle. Then, you submerge the bottle in the water until the bowl is the only piece of the bottle that is not submerged in water. As you burn the marijuana you pull up the two litre bottle until it is filled with the sweet, sweet marijuana smoke. When the bottle is filled it should be a dark grey color because the smoke will be so thick. Next you take the bowl out, put your mouth over the bottle opening, and push the bottle down, thus quickly filling your lungs with a massive toke. If you do Hiroshimas correctly, it will only take a few hits to fuck you up.

An accident that results while performing the Japanese Blindfold and Fukushima release valve. Only once thus far in history a groom slipped on a piece of sashimi while sitting on his bride's head completely enveloping it all the way past her mouth with his anus. When he farted the air could not escape her mouth, and blew her eyes out of their sockets with the force of a nuclear explosion.

When you take a shit so large the people from the outside can smell it. It usually occurs when you eat some spicy Indian food or maybe spicy Mexican food. But the easiest way to get a Hiroshima is to take a bunch of laxatives and glue your ass together
Carl: “Dude don’t go in there, Stephan just took the Hiroshima.”
Dude: “I can smell it from here. We need radioactive suits to clean it up.”
