Meaning
An upward triangle sitting on a flat bar, the eject button once used to pop discs and tapes out of a player. Literally it means remove or take out.
Online it has become a playful “I’m out”, used when leaving an awkward conversation, a noisy group chat or a bad situation: “This meeting could have been an email ⏏️” It can also mean safely removing a drive. Pair it with 🏃 or 🚪 for a quick exit.
