McRefugees is a neologism and McWord referring to those who stay overnight in a 24-hour McDonald's fast food restaurant.
The term was first created in Japanese language: マック難民. That term had been largely replaced by ネットカフェ難民, literally "net cafe refugee". In Japan, most McDonald's restaurants are operated around the clock. Due to unemployment and high rents and transportation costs in Japan, McRefugees choose to stay at a McDonald's overnight.
The phenomenon and word spread to Hong Kong as 麥難民, where some McRefugees play video games and are known as McGamers. McDonald's opened 24-hour branches in mainland China in September 2006, which quickly attracted McRefugees.
In early October 2015, the death of a woman in a 24-hour Hong Kong McDonald’s restaurant in Kowloon Bay brought attention to the problem of McRefugees. McRefugees can be found in other 24-hour branches as well.
