Leafer Madness 

When large crowds of people, particularly from an urban area, head to smaller towns each fall to see the beautiful foliage causing large traffic jams

madokaism

One of the two big otaku religions, on the same level but more niche that haruhism. The basic premise is praising out lord and savior Kaname Madoka for saving anime in 2011, and the magical girl genre as a whole despite at the same time ruining it.

Guy 1: I'm catholic
Guy 2: oh cool I'm a follower of madokaism
Guy 1: what

Guy 2: *rips off shirt revealing homura t shirt, shorts that say "sayaka did nothing wrong" and "kill kyuubey" cap and runs away screaming the lyrics to connect*
Guy 1: wtf.....everyone knows that haruhism is the real weebligion.
