I quite like ‘isms’. Got a new one today reading John Berger’s essay on Jackson Pollock (See also this post on Pollock):
Pollock was highly talented. Some may be surprised by this. We have seen the consequences of Pollock’s now famous innovations – thousands of Tachiste and Action canvases crudely and arbitrarily covered and ‘attacked’ with paint.

There it is: Tachiste.
