Muggle (dictionary)
From BoyWiki
Muggle is a term used by many in the boylove community to refer to anyone who isn't a boylover. The term is taken from the Harry Potter series of children's fantasy novels by J. K. Rowling. In the series, the magic-using wizards refer to ordinary, non-magical folk, as muggles.
This term has been popularized recently by its use by Appy on The Appy Show broadcast on Sure Quality Radio, although its usage on BoyChat predates this program.
