A little background.
Some doujin artist in Japan made a little series of comics with Tsuruya from Haruhi, except they messed up her name on purpose as "Churuya," and had her doing all these stupid things (related to smoked cheese?) that ended with the line "Nyoro~n."
Tsuruya NEVER says "Nyoro~n" in Haruhi.
Anyway, it became a stupidly huge internet meme, both in Japan and the USA (parodies are everywhere, melonbook's new mascot says "Mero~n")
This kid killed himself and wanted Churuya at his funeral it seems.
