It’s the vibration that’s made from styrofoam rubbing or biting on undercooked green beans. It can also come from walking on fresh snow. The vibration can almost be incapacitating like if a baby were crying in your spine.

    There apparently is a named phobia for Styrofoam, specifically: Styrophobia.

    Someone I knew called things like green beans “squeaky”.
