EEFI

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.

Eefie

1. a name given to a complete dumbass that oftentimes believes everything that they are told even when presented with information that proves they are wrong with hard facts.
2. a person that reaches a certain level of idiocracy and immaturity so much that it affects those around the person dramatically.

Lovetta is such an eefie for thinking that urbandictionary was a real dictionary and could actually be used and classified as something she "researched."

Eefin (Walmart edition)

Literally not the cutest person ever. Anyone who says otherwise is automatically saying no other human has ever existed. I know what you're thinking, and no I did not write this to prove a point. This is officially written by the legend-dairy John Decengre III of New Jersey.

To the person reading this (yes this actually has a purpose),

No need for any further explanation, you're officially ruled cuter by the public, judge, and jury. I rest my case. ;)
