Proc

A proc in Star Trek Online and other MMOs is a term used to describe a special effect or bonus that is activated on a piece of equipment, generally with a low percentage chance to happen. It is short for the common programming term procedure. Many younger people often tend to want to interpret terms that are unfamiliar to them as acronyms and as such want to backronym the term proc as being for "Programmed Random Occurrence", but that is not the origin of the term.

An example of a proc would be the 2.5% chance bonuses that are applied to starship weapons, such as a Beam Array.
