Japanese War Tuba

Japanese Devil Dog

When you're having sex with a girl in reverse cow girl position and then she gets up and shits on your dick. Then you cum on your own dick and she sucks it all off.

My wife wanted a japanese devil dog. I divorced her the next day.

Japanese Rain Monocle

Close to the Japanese Rain Goggles but your man only has one nut sack that drops. Picture the Monopoly guy or Mr. Peanut.

I was trying to give my girl the Japanese Rain Goggle but it was cold and only was able to give her a Japanese Rain Monocle instead.

japanese whammy bar

When a man has an extremely large boner and the female/male (depending on preferences) grabs the large boner and bends in a very obstructive fashion, which may lead to a crack in the pelvic area.

I was at my friends and he was having a very pleasurable dream and so i decided to give him the japanese whammy bar.

Japanese War Fountain

When you eat nothing but chili for a couple of days while holding off the urge to take a shit and when it finally becomes unbearable you stand over your other (preferably in a bathtub) and spray your fountain of explosive diarrhea all over them.

My relationship with my old lady went to the next level when she let me give her a Japanese War Fountain
