Verb - The act of finding an amusing acronym for something. Coming up with some amusing acronyms vaguely based on the concept, then using a thesaurus to fill in the blanks. Leads to very contrived or stretched expansions of the acronyms.

May end up with decidedly dodgy acronyms, or intentional double-entendres. Generally adds to the bullshit-bingo used in project meetings.

IT and new media organisations come up with dodgy acronyms almost as a competitive sport.
