“Crazy times we are living in. I used to cough to hide a fart. Now I fart to hide a cough”

Cough fart ... When someone coughs to hide a fart with devious intent” was entered in the Urban Dictionary on December 2, 2010.
     
The 2019–20 coronavirus outbreak reversed this. “I remember the time when we used to cough to hide a fart. Now we fart to hide a cough” was posted on Twitter by Kenan on February 28, 2020. “I use to cough to hide a fart..Now I fart to hide a cough” was posted on Twitter by Djsoapytitwank on March 7, 2020. “Crazy times were living in. I used to cough to hide a fart now I fart to hide a cough” was posted on Facebook by Mikey Fressh on March 12, 2020.
   
“Cover up a fart” was used slightly earlier than “hide a fart.” “People used to cough to cover up a fart. Now they fart to cover up a cough!” is a related saying.
