The phrase refers to instances of dressing up as the Dragon Ball character Android 18 where the costume or associated imagery is sexually suggestive or explicit. This often involves interpretations of the character’s attire that are more revealing than her standard appearance in the anime and manga, or the posing and presentation of the cosplay in a manner intended to be sexually provocative.
The existence of such content reflects the intersection of fandom, cosplay, and the adult entertainment industry. Characters from popular media often become subjects of adult-oriented works due to their pre-existing recognition and appeal. The practice allows individuals to express creativity, engage with a character they admire, and participate in a subculture that explores themes of sexuality and fantasy.
