Main character (of X)
Also known as: Main character syndrome
The person whose tweet, situation, or behavior the entire app is talking about on a given day — usually unwanted.
In depth
Every day on X there's a "main character" — one person whose tweet sparked viral controversy and is being quoted, dunked on, defended, or mocked by thousands of accounts. Most main-character moments are unintentional: someone posted a hot take that backfired, made a mistake, or got caught doing something embarrassing.
Becoming the main character usually drops follower count by 5-30% as people who disagree mass-unfollow. The few who like the take might follow but typically don't stick. Net effect: usually negative for the main character.
Deliberately seeking main-character moments ("I'll just post something outrageous to get attention") almost always backfires — X's algorithm flags repeated controversy-farming and downranks the account. Real main-character moments are accidents you survive, not goals.
Example
A CEO's "if you don't want to work 80 hours, don't apply" tweet might make them the main character for 36 hours — viral coverage, then a hiring slowdown for the next quarter.
