Jeej is a term that Chloë popularized herself. She first used it in a caption on Instagram ( https://instagram.com/p/zJVp8UDnWs/
), which spurred debate over whether the bizarre word was a typo, a reference to an existent Dutch phrase ( >>>/chloe/66168
), or a word invented by Chloë similar to faboost.
After a while, she used the word again in another Instagram caption ( https://instagram.com/p/078AlYDncJ/
) and made further reference to it on Twitter ( https://twitter.com/ChloeGMoretz/status/583299480772050944
). This added to the confusion around the word, as it was now clear that she was using it intentionally but still refraining from giving it a strict definition.
At this point in time, the meanings and origins behind jeej are still debated, but it has spawned many creative and hilarious OC's as well as a myriad of jeej-related tweets (some of which Chloë has even taken the time to reply to).
