H-Digit
The H-Digit is the one who’s so plain you wonder if they’re even real.
My friend is the H-Digit of our group. He eats the same lunch every day and still doesn’t know who Drake is.
She’s the H-Digit of the office. She sits at her desk and doesn’t even talk to her coworkers.
He’s the H-Digit of the school. He’s been there for years and still doesn’t know what a pop quiz is.
