A sigh jinx is when two or more people sigh at the same time, and one person yells Sigh jinx! Thus causing the other sighing members to be rendered silent until their name is said three times in a row.
Sean and Jessica sighed at the same time. Jessica yelled Sigh Jinx! At the top of her lungs rendering Sean silent until she said his name three times.
