Noun. A moshery is a place where moshing takes place. While "mosh pit" is the name for the specific area in which the actual moshing takes place, a moshery refers to the building or surrounding area (club, arena, basement, back seat of a car, one's mind, etc.). The term "mosh" originated in the early 1980s, and the first documented use of the word "moshery" came around 1986-7 in a high school student's music column, Uncle Louie's Moshery, in Whitmer High School's Panther's Pause newspaper (Toledo, Ohio).
