Etymology

Cognate with Yiddish: גרױסקצין

In summary

According to the Kluge, the word is first attested in Berlin's 19th c. Hochsprache as an adjective synonymous with 'he who wins a pissing contest'.
According to the Duden, the substantive Großkotz (“a bighead, a cocky person”) came first and out of Yiddish גרױסקצין (groyskotsn, “a filthy rich person or a pompous git”), derived in turn from קָצִין (katsín, “a leader or officer”), of uncertain etymology but perhaps related to קצה (“end or tip”) in the sense of 'end of the chain of command in the army'.
