A lesbian meme which started when a
tumblr user attended a premier of the 2015 movie "Carol" and made a post mentioning the amount of heterosexual elderly
people who also attended. In the post, they mention how a certain couple in particular sat in front of them and how, halfway through the movie, the
woman leaned to her husband and said "Harold, they're lesbians". This now is most often used to caption a photo or gif set involving a fictional or nonfictional lesbian relationship.
