What does the "with-outs" mean ?

Black Day events have snowballed, with a major matchmaking service this year providing an evening of speed dating where the dish of choice is sushi blackened by squid ink. An on-line company for movie tickets sponsored a speed eating competition of black noodles for those who bought single tickets for the latest films. "It is depressing enough going to the movies by yourself," said Shin Youn-joo of the company called Max Movie. "We just wanted to spread a little joy to the 'with-outs'."

What does the "with-outs" mean here? Thanks.
