In the past, it was sometimes used as a synonym for antimatter. Another term you might see in older materials is CT, or contraterrene, matter. The paper in which it was first pointed out that negative mass was not necessarily a contradiction in terms was published in 1957, so any use of the term before that probably means what we today would call antimatter.
Nowadays the term is usually used for a hypothetical form of matter which has a negative mass. Some physical theories allow for the existence of this kind of matter, which may mean either that it is in fact possible, or it isn't and the theory is incomplete.
