123456789 is just a bunch of numbers. Why tf are you looking it up?
They can be used as a fake phone
number, either for
trolling or for writing a story, if you're too damn
lazy to think of something else.
Examples:
a. Person1: Can I have your phone number?
Person2: Uhhh... Sure. 123456789.
b. "
Bob went back to his desk after the
break. On his notebook he finds a note that reads: "Call me. 123456789 ;)". He immediately recognizes that the note had been written by his best friend,
Mark."
