Where does come from?
The banana emoji, as its officially called, was first introduced in 2010 under Unicode 6.0. While it's a popular fruit, the phallic likeness of the banana emoji quickly lent it as a symbol for penis on social media and text messages.
In the late 2010s, popular media often noted the sexual suggestion of the banana emoji, with many articles instructing parents on the "secret meanings" of seemingly innocuous emoji like the banana in their children's online communication.
As a representation of the penis, the banana emoji joins the eggplant emoji, which is even more widely used in this way online.
Who uses ?
On social media, people may add the banana emoji to mark or emphasize content discussing sex or penises, especially when posting revealing selfies. Though sexual, the emoji often carries a playful or humorous tone.
Other uses of the banana emoji are more innocent. People use the emoji when talking about the banana as a fruit, food, and flavor (e.g., I'm craving a strawberry & banana smoothie🍓🍌).
The banana emoji is also used to suggest "crazy," drawing on the idioms That's bananas! or Go bananas! For instance, "The overtime of the football was absolutely 🍌🍌🍌!". By extension, people may use the emoji to express extreme excitement, as if they are "going crazy" over something (e.g., I 🍌 can't 🍌 wait 🍌 for 🍌 the 🍌 Beyoncé 🍌concert).
Cartoons have long employed the gag of characters slipping on a banana peel for physical comedy. Texters and tweeters sometimes draw on this gag when they post, say, "Don't slip up 🍌" or "Break a leg 🍌" as a way of wishing someone luck or digitally "crossing their fingers."
Bananas, finally, are associated with primates, and so people may incorporate the banana emoji in content dealing with monkeys or when using the idiom monkey business, making the banana emoji a suggestion of mischief.
