Sarah Jessica Parker (SJP) says "rabbit rabbit" as part of a superstition that is believed to bring good luck if said as the first words on the first day of the month. This tradition, believed to have British origins, involves saying "rabbit rabbit" exactly at the start of a new month before saying any other words, which is said to invoke good fortune for the rest of the month. SJP has shared this ritual on her social media for many years, and it inspired her to collaborate on a clothing line that includes the phrase. The superstition is rooted in the idea that rabbits symbolize good luck, fertility, and life, with rabbits being considered lucky for over 2,000 years. Saying "rabbit rabbit" is believed to double the luck because words are considered symbolic and powerful. SJP and others consider it a fun and meaningful tradition to start a new month positively, sometimes even incorporating related rituals like burning incense. This folklore has been popularized and referenced in culture for more than a century and was even used by President Franklin Delano Roosevelt for luck. Though its exact origin is unclear, it remains a charming superstition with widespread appeal, especially in English-speaking countries.
