The phrase identifies a type of disguise intended for celebratory seasonal events, specifically one that replicates the appearance of a deep-sea creature characterized by a bioluminescent lure. For example, an individual might wear clothing and accessories designed to mimic the dark coloration, large mouth, and prominent light-producing appendage of this marine animal.
The significance of this type of attire lies in its ability to provide a unique and often visually striking alternative to more commonplace seasonal disguises. Historically, depictions of unusual or frightening creatures have been prevalent during such festivities, and this particular design aligns with that tradition while introducing an element of natural history and potentially sparking curiosity about marine ecosystems. The use of such a design can offer a refreshing and creative expression, distinct from conventional choices.
