Essential Elements of Friendly Information (EEFI) are critical aspects of a friendly operation that, if known by the enemy, would subsequently compromise, lead to failure, or limit success of the operation, and so must be protected from enemy detection.
The location of the water balloons was an EEFI to operation "Soak Suzie." Hobbes failed to watch his EEFIs and divulged where Calvin stored the water balloons during a tummy rub. The mission resulted in utter failure.

Get the Eeffy mug.A typical dutch name for a girl. Eefje’s are usually very smart but they are very sneaky. They will eat your brains out and then spit on your tits. Most Eefje’s don’t have any friends so they eat lunch with their pets.
Girl: Hey look at that Eefje.
Boy: Omg, look at that sad piece of sneakyness eating lunch with her pet.
