white refrigerator
A white refrigerator. If someone has a white fridge in their kitchen, this is a signifier that they are likely poor or lower class. Conversely, someone who has a stainless steel fridge is less likely to be poor. However, many households who previously had a white fridge as their main fridge, and may have accumulated income to buy a better fridge, keep their former still-functioning white fridge in their garage, basement, or hallway as a secondary fridge in addition to their better primary stainless steel fridge.
I went over to his parents' house and they still had a white refrigerator... I think he grew up poor.
