Referring to the
plastic or PVC transparent door curtains most commonly found at the entrance to varying commercial and public spaces. Although initially designed to keep out unwanted insects , in the age of the global pandemic, these curtains or "flaps" encourage a significantly higher risk of viral contagion due to their large surface area which, by design, requires the
skin contact of the hand, arm or in some cases
face in order to operate.
Due to the inherent dankness of such threshold systems in the topical context has led to their addition to the cannon of COVID related catch phrases.
First coined in Wellington, New Zealand in
late 2020 by local social personality, Rohanah Sos.
