The term was first created in Japanese language, which originally means "net cafe refugee", people sleep in 24-hour Internet cafes or manga cafes. In Japan, most McDonald's restaurants are operated around the clock. Due to unemployment and high rents and transportation costs, McRefugees are forced to stay at a McDonald's overnight.
The phenomenon and word spread to Hong Kong, where some McRefugees play video games and are known as McGamers.
