The act of verifying or confirming who someone's main is — their top-used character in a game, their primary romantic interest, or their #1 stan target — usually to validate, challenge, or clown them about it. In gaming, a main check exposes whether you're truly committed or just cosplaying as a fan. In fandom spaces, it's a quick loyalty verification: who do you actually ride for? The main check is often playful but can get serious when people's claims don't match the receipts.
Before joining the team, they did a main check and found out he'd only played that character twice — instant credibility loss.
