Up! Button Emoji Meaning

The captialized word UP with an exclamation point after it, shown enclosed in a square. Originally intended to denote leveling up in a game, it can also broadly indicate that something had increased, improved, been updated, or moved upward in ranking or status.

Typically depicted as white text within a blue square background, though Facebook's design has a green background.

This emoji predates the inclusion of emojis within Unicode. It was first added to early Japanese emoji keyboards by SoftBank in 1999.
