Don’t be a #maskhole
If you have a hoard of masks, keep a few and donate the rest, you do not need them if you are not sick unless you are in VERY close quarters with people.

Is it appropriate to call someone wearing a mask who clearly doesn’t need to be wearing one a maskhole?

It’s the “Don’t Be a Maskhole” Edition! What should the federal government be doing to fight coronavirus? What are the strengths of a democracy vs an autocracy during a pandemic? And a new report finds significant problems with FISA applications.
The “Don’t Be a Maskhole” Edition
State and local governments are on the frontlines of the fight against the coronavirus. But there’s a lot the federal government can, and arguably should, be doing. What is the pandemic showing us…

Guidelines and advises on how to wear a mask have also failed as many people still don’t wear one or wear it the wrong way. Step out at any point of the day and there will be people with the mask covering just their mouth, or chin, or it graces their neck (just for the heck of it). Photographs on social media even show people having tied them at the back of the head. Four months into the lockdown and continuous messages on how to be safe, the mask is still not finding its place. And now we do have a word for such people who defeat the purpose of masks. Maskhole is the word that The New Yorker has devised for such individuals.
