The Snapewives (singular: Snapewife) were a collection of middle-aged women who worshipped the character Severus Snape, of Harry Potter fame, as a being on the astral plane. This cult was primarily focused online, though informal, real-life meet up (Snapecons?) have occurred.
The cult of the Snapewives was most active around the mid-late noughties, especially during 2007, though devoted blogs can still be found with posts as last as 2010.
Practices of the Snapewives include: building domestic &/or online shrines to Snape; making collages of Snape; photoshopping pictures of oneself and Snape together; marrying oneself to Snape, complete with wedding vows and faked photos; writing disturbing Snape-focused fanfiction or poetry (bonus points for including a self-insert to do dirty things with Snape); writing letters to Snape; discussing Snape with other Snapewives (bonus points for rationalising away all his flaws, and insisting he's a poor woobie who just needs a hug); attempting to channel the "spirit of Snape", especially popular with group meetings.
The most (in)famous 'wives include SeverelyObsessed/Lady Darkness, and Snapemaniac, though both are quite inactive nowadays, and many of the forums and blogs hey started have been taken down. The whole hilarrible
fiasco has been well documented on JournalFen at www.journalfen.net/community/fandom_wank/1015949.html?thread=134403469#t134403469
Alice: Bob, quick, you have to see this! Some livejournal user just wrote a fanfiction about her and Severus Snape being set on fire whilst having sex!
Bob: God-damned Snapewives ...
