The 2019–20 coronavirus outbreak caused many to socially distance themselves from others and to quarantine themselves in their homes. Some people held “quarantine parties.”
 
“Quarantine Party!! This might top all my themed parties I did in my 20’s except this time no one is invited” was posted on Twitter by Lisa Kasha on March 12, 2020. “Quarantine party at my place on saturday! no one is invited, don’t bring your friends” was posted on Twitter by guilloteen a few minutes later on March 12, 2020. “I am having a quarantine party, but none of you are invited” was posted on Twitter  by JC latr on March 12, 2020.
