Ever heard that it’s good luck to say rabbit two or three times on the first day of the month? “Rabbit rabbit” was a top-trending Twitter topic Friday, the first day of September.

There are different variations. Some people say, “bunny, bunny, rabbit rabbit.” Others say, “white rabbit” three times. Either way, the superstition originated in Great Britain and North American, according to the ever-reliable Wikipedia.

Unfortunately, there isn’t much information about how the superstition got started. But the first time is was recording as being said was in the 1909 edition of the quarterly scholarly journal “Notes and Queries” and notated in “A Dictionary of English Folklore,” as People Magazine noted last month.

“My two daughters are in the habit of saying ‘Rabbits!’ on the first day of each month. The word must be spoken aloud, and be the first word said in the month. It brings luck for that month. Other children, I find, use the same formula,” a section of the text read.

Rabbits represent fertility and prosperity. It’s likely because rabbits reproduce fast.
