:O

Beginner 📱 Gen-Z / Internet Slang

Definition

The classic emoticon representing a gasping open mouth, deployed when text needs to convey shock, surprise, or excitement. A digital ancestor of today's emoji, this simple combination of colon and capital O has been expressing disbelief since the early internet era when our communication options were charmingly primitive.

Example Usage

Sarah: I just won tickets to see Taylor Swift! Emma: :O NO WAY!
