Mostestmesterfederededereded
For when you’re trying to one up someone (I.e. “I love you the most”) but you need a word that is bigger than “the most” so you just start slapping random syllables onto the word (I.e. “Most —> “Mostestmesterfederededereded”) so therefore, you’re argument is valid and you can do something even more than the most.
“You remember how I said little ceasers pizza has the most sauce on their pizza I’ve ever seen? Well, turns out that dominos actually has the Mostestmesterfederededereded amount of sauce on their pizzas...”
