What does "dead tie" mean? Could you give me some examples?

"Dead tie" means the same thing as "tie," which is that there is no single winner for that specific competition or contest. This term has more emphasis than "tie," which is used more often. Ex: A: Who's your favorite family member? B: It's a dead tie between my mom or grandma. Ex: There's no winner for this race. It's a tie between two contestants.
