A person who always insists that the newer episodes, including past season 9, of Spongebob Squarepants are forgettable garbage compared to its earliest episodes, specifically before the first Spongebob movie.

In the same vain as a Genwunner is to Pokémon.
Person 1: "The newer episodes of Spongebob are such garbage. Goes to show you how much pre-movie episodes will always be superior."

Person 2: "Ok Spongeboomer."
