jinxers
Bringers of misfortune
People who jinx things—who bring bad luck or cause misfortune by their presence, actions, or words.
The term often appears in sports contexts, where fans worry that premature celebration or overconfidence will doom their team: Don't say we've already won—you jinxers will ruin everything.
