The phrase refers to attire intended to replicate the appearance of Orcinus orca, specifically for the Halloween holiday. An example would be a black and white suit designed to mimic the coloration and shape of the marine mammal, typically worn for costume parties or trick-or-treating.
Such a costume allows individuals to express an appreciation for marine life and the apex predator of the ocean, offering a recognizable and often striking visual. Historically, animal costumes have been popular during Halloween, with this particular representation potentially gaining traction due to increased awareness of ocean conservation and the charismatic nature of the species.
