MEME REFERENCE

Fast Flash

Use when someone arrives, responds, completes a task, or disappears with implausible speed.

What it expresses: An action's turnaround is exaggerated as superhero-level velocity.
Example: You send a friend a restaurant link and they book the table before you finish typing the next message, so you reply with this.
When not to use it: A contractor delivers two weeks late; a speed reaction would contradict the actual delay.
