Simply put, explosive diarrhea--the kind that explodes all over the bowl. Accompanied by gaseous emissions, swearing, perhaps an "AAAAAHHHHH" in relief, and then a horrid stench within about 3 seconds--sending innocent bystanders running from the john.

If the Havana omelet occurs after eating too much hot sauce, have a tub full of icewater nearby because the sufferer may scream in agony from the third-degree burns to the lower intestinal tract.

Get the havana omelet mug.
A case of diarrhea that creates a series of loud splashes
in the toilet water. Often accompanied by an escapee. Try using a camo cough with an Astaire.
after eating his aunt's renowned recipe of spicy jerk chicken, a havana omelet came back and struck fat eldon with a vengeance!

Get the Havana omelet mug.
To splatter diarrhea all over the inside of the toilet, including the under side of the seat.
After a night of cheap booze and chili dogs, I sure did create a masterpiece of a Havana Omelet in the toilet.
