Combines the word Yak, meanning a big hairy animal, and "sich". Sich is the administrative and military centre for Cossacks and especially the Zaporizhian Cossacks. It is derived from the Ukrainian word siktý, "to chop", meaning to clear a forest for an encampment, or to build a fortification with the trees that have been chopped down.
Together this word means to chop the main area of the Yak, the penis, off and fill the hole with the diced member.
