The term "Hiroshima Cluehammer" alludes to a hypothetical, inevitable event so detrimental to furry fandom and its reputation that it would finally "(wake) people up to what idiots they've been for the things they've allowed and tolerated in the fandom." It was coined by Richard Chandler in the alt.fan.furry post announcing his departure from the fandom in 2001.
In the ensuing years, the term has mostly — though not uniquely — been used by Xydexx in satirical attacks on the concept and its author, to the point where one person associated it more with him than with Chandler.

- In his post, Chandler also expressed the belief that "Furry Fandom's potential will never be realized with the current crop of losers and misfits who infest it and drag it down." This section of the post aimed at those supporting fursuiter Ostrich and plushophile FoxWolfie Galen, whose interviews featured in what many saw as unfavorable mainstream media coverage of the fandom — in particular the 2001 Vanity Fair article Pleasures of the Fur.
