Evil Little Fat Folk -
A short, fat person with a terrible disposition.
"That woman in the plus size section was so rude to me!"
"I know, she's such an E.L.F.F.!"
Examples of E.L.F.F. worthy mention:
-that mean woman at the gas station
-that guy at the toll plaza that won't ever let you slide, not even for a penny
-Rosie D., who makes the list despite height
-that guy who did your taxes last year that made you fill out the forms twice
-that woman that ALWAYS has something rude to the server right before they wait on you
And the list goes on...
