This olive salad was on its own level of greatness that no other food item in history has ever achieved. People needed to create a new word to describe the taste of greatness it had....... delicious, scrumptious, tasty, all these words were sub par for what it was and something that great could only be described by using a word created and named after itself; Olive Salad.
From this day forth, should anything be so remarkably great, it shall be desribed as being olive salad.
Person 2 - "I know what good food is like and I know that sammich is good."
Person 1 - "I am sure you have ate good food many times before. Your mistake though, is that you think this sammich is good, when in fact this sammich is olive salad!"
Person 2 - *bites sammich* "OMG this sammich IS olive salad!!!"
