This slang term refers to a second-hand smart fridge bought from a junkyard by a
middle-class family who wants to
experience owning a smart fridge but just cannot afford one. Once having arrived at the family's home, this smart fridge ends up (
experience some kind bug causing it) having its date setting stuck on dates coinciding with the fasting month of Ramadan like Tuesday, April 2nd 1991 or Tuesday, April 2nd 2024. Hence, the family can only eat from the smart fridge at night, at least for the first several days upon the arrival of the smart fridge.
