alphabet title
n.— «Four world champs may be confusing enough for some, but then we can add the WBU, IBO and IBA among others. The “lesser” belts such as the WBU and IBA are often referred to as alphabet titles and are not given much credence by the informed boxing fan but how on earth is a casual fan meant to know who is the best in each division?» —“Get rid of the alphabet boys” by Craig MacKay BritishBoxing.net (United Kingdom) Feb. 11, 2008.
