As stated by 126.96.36.199, I always thought it was a jinx that backfired, as opposed to a jinx that causes things to backfire; if my memory serves me correctly, 'backfiring jinx' was not capitalised. If it was a jinx that backfired rather than a jinx that causes things to backfire, is it possible that there are 'backfiring charms' and such? If so, I presumed that Ron Weasley would have had this happen to him in Chamber of Secrets. This theory is supported by the fact that the Trading Card designated to depicting Ron's malfunctioning wand is titled "Backfire!". Hunnie Bunn (talk) 17:37, July 8, 2012 (UTC)
We need to be rid of this page
I'm absolutely certain that when the words "backfiring jinx" were in the books, they were not refering to a particular type of jinx casted, but rather an unspecified jinx that happened to be physically "backfired". Therefore, I highly suggest that this entire page should be deleted for its irrelevency.
