FISH

An abbreviation for "first in, still here." The term is a tongue-in-cheek reference to the first in, first out accounting method. It refers to a company that keeps its inventory for a long time, often because of poor sales. Ultimately, this may render inventory obsolete. A company dealing with FISH may be in or near financial trouble.
