Meme: "Because, magic"
Originator: SFF.se Harry Potter fans.
Cultural Height: The wave has yet to crest!
Currently active: Yes
Background: In October/November 2011, SFF.se approved Harry Potter as a Q&A topic. Since that time, hundreds of users, perhaps thinking they were clever and iconoclastic, have answered "Because, magic!" whenever a Harry Potter question is posed. It is meant to suggest that anything which happens in the Harry Potter universe can be fixed by magic, including, presumably, feats that defy normal magic, such as healing wounds from Dark Magic, and even Death itself. This is not compatible with Harry Potter canon, and J.K. Rowling has said many times that "magic doesn't and cannot fix everything."
The application of "Because, magic" is not encouraged and occurs mainly with newer users. However, occasionally a high/higher rep user will whip this winner out of his/her war chest. Upon encountering "Because, magic", the community typically 1) mocks the phrase, 2) rolls their collective eyes, or 3) pretends to answer every other question on the site with "Because, magic", even when magic doesn't even exist in a given universe.
