groupuscules groupustules

"When I read his description of the sects within Jansenism, the Augustinian
movement in seventeenth century France, I remember being struck by the
comparison with Bolshevik sects of the 1920s (but also some left-wing groupuscules—Maoist, Trotskyist, etc.—that I came
across in the U.S. in the late 1960s and early 1970s)."

¬ Mitchell Cohen, The New Atheism: An Interview with Mitchell Cohen

Groupuscule is a French term describing the political phenomenon in which the far left and right tend toward a proliferation of tiny groups. This is particularly common in Anarchist, Fascist, Stalinist and Trotskyist groups.

I'd like to suggest "groupustules" to describe the usenet phenomenon of predominantly far right, objectionable woo-woos, sock puppets, and trolls.
