Whatever you do don’t get the red onesie: Redshirt is a slang term for a minor stock character in an adventure drama who dies violently soon after being introduced to dramatize the dangerous situation faced by the main characters. The term originated with the science fiction television series Star Trek, from the red shirts worn by Starfleet security officers, who frequently beamed down with a landing party, only to become the first, and sometimes only, victims within the party.
