An internet forum troll, particularly one prone to right-wing rants against women, gays and liberals. Etymology of "zagoshe" comes from a combination of the (wing)nut-filled candy bar "Zagnut" and douche. Also spelled "zagouche" but for whatever reason, the "zagoshe" spelling is the one most commonly seen.
The moderator of the forum locked the thread, thanks to yet another zagoshe trolling around the politics threads.
