Yes. In my parents' day it referred to ultra-nationalistic, totalitarian movements, highly militaristic and usually predicated on the supremacy of a single leader. The term was one that Mussolini used to describe his movement, his party, and later his form of government in Italy, but it came to embrace Franco's movement in Spain, Naziism and Germany under Hitler, and a host of other regimes (e.g. in Roumania, Hungary Vichy-ruled France) and movements (Mosley's in the UK, Coughlin's in the USA).

In our own day the term can rightfully be applied to neo-Fascist and neo-Nazi movements which have sprung up in the USA and Europe. It can also be correctly used to describe Chile when it was under Pinochet's rule.

Yes, the term "Fascist" has be overused and abused. But that doesn't mean the term has been rendered useless. (Note correct use of a double negative: "doesn't" + "useless." I believe the name for that literary device is "litotes.")
