It doesn't piss me off, nor is it a term, but it's getting a little odd how prevalent the delusion that "cartoons are real in another dimension" seems to be getting.
There's the "waifu" subculture, "pop culture paganism,"
people marrying holograms being described as "interdimensional" love, SJWs who think men making a female character sexy is "rape" because "she didn't consent to it in real life," and then of course there's Chris and the "Dimensional Merge" (which is still "in progress").
Like I said in the waifu subculture thread, this wasn't a thing before Current Year.
