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 someone goes to the gym and spends 90% of the time on their phones scrolling through social media

when you jacking off you call your mom to your room then you hide behind the door and when she walks into the room you unload all over her

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

when you are jacking off and you call your mom to your room and when she comes you run behind your door and when she opens the door you unload all over her

This is when you are banging a girl and right before you are about to cum you pull out, jump off of the bed onto your back and blow your load everywhere.

A sex act. When making love to a woman and close to orgasm, the male pulls out, fakes orgasm, and spits quietly on the girls back to mimic the feel of ejaculation (similar to The Houdini). When the girl turns to face the male, he ejaculates on her face. As she tries to turn away, horrified, the male grabs her face, turns, and farts into her mouth. The male continues his spin by punching the girl in the mouth. It is called "The Hiroshima" because it leaves you utterly devastated.
