Muscedere and his followers took to calling themselves the "no surrender crew", after an ultra-violent fraction in the Irish Republican Army opposed to the Good Friday Agreement of 1998, because they refused the orders from Houston to surrender their patches, saying they were going to stay on as Bandidos despite Pike's decision to expel them. Outlaw bikers attach enormous symbolic importance to their patches, which show which club they belong to and what their position is within their club. The patches belong to the club, not to the men wearing them, and must be returned at once if a member is expelled or resigns. Within the world of outlaw bikers, it is considered extremely offensive for someone to wear the patch of a club that they do not belong to, and violence usually results when someone wears a patch of a club that they are not a member of. The Bandido patch was of a Mexican bandit. Donald Chambers, who had founded the Bandidos in 1966, liked the cartoon character of the Frito Bandido who was used in a series of 1960s TV ads to promote Frito-Lay chips. Following complaints from Chicano groups that the Frito Bandido was promoting negative stereotypes of Mexicans, the ads were dropped, but Chambers had adopted a version of the Frito Bandido character, whom he called "the Fat Mexican", as the patch for his club as a way of insulting Chicanos.
