Pathanamthitta does not exist
Pathanamthitta does not actually exist is a meme used to make fun of Pathanamthitta, one of the 14 districts of Kerala.
Usage
Origin
The origin is said to be from Facebook groups. When people started making memes on stereotypes of different districts, Kannur has bombs, Kollam has misers, Thrissur was crazy about Elephants, Pathanamthitta stood out by not having much to say about it. This evolved into the meme saying that the district Pathanamthitta doesn't exist.[1]
The meme must have also had influence from "New Zealand does not exist" meme because New Zealand was often missing in maps.
