how about Herculean. I love that term.
And there's always "Ungawa". In the old Tarzan movies that Johnny Weismuller used to star in he'd yell "ungawa" and it seemed to have different meanings. One time it meant for a herd of elephants to build a bridge, and one other time it meant for a lion to attack a bad guy, and one time it meant for Cheetah to give Tarzan the reacharound.
