Mask Wearing for Dummies 

The long-overdue title for millions of anti-maskers and maskholes around the world, whose selfish actions only prolong the coronavirus pandemic on earth, and lead to more infections and deaths—they need to come to terms that their constant refusal to don a face mask in public has serious consequences, such as fines, push-ups, and jail sentences (or even caning or deportation in some extreme cases).

The author of “Mask Wearing for Dummies” hinted to his publisher that he’s concurrently writing “Lockdown for Dummies” and “COVID-19 Vaccines for Dummies” targeting at millions of covidiots, particularly the diehard Trumpists and hardcore QAnonists from the red states, who get most of their corona advice from their Maskhole-in-Chief.

Dummies Get Baked 

Usually used to clown on a person who refuses to use common sense to solve or deal with a problem or issue, thus, paying a severe consequence because of his or her arrogance, ignorance, and lack of knowledge.

Man I told Timmy not to hook up with that trick from the block. She's got STDs. Not to mention her brother is a hitman.

But guess what, Timmy hit it anyways..."Dummies Get Baked."
