Scandinavian Shotgun 

Similar to the German Cannon, but when struck, the projectile takes on a spray pattern.

"I didn't know she had so much Mexican Food, so when I fired the German Cannon, I ended up firing a Scandinavian Shotgun."

Nicaraguan Shotgun 

When explosive diarrhea combines with low hanging testicles and the spread of the initial diarrhea blast is wide enough that you actually poop on your own testicles

Dude, it was so hot yesterday that after I ate that bad mexican food, I sat on the toilet and had a Nicaraguan shotgun. It took me like ten minutes to clean off my balls...
