Backstreet Boys Reunion Tour 

In the wake of the CO-VID 19 pandemic, which occurred in the spring of 2020, the Youtube gods attempted to crack down on the hysteria by demonetizing content that contained the word 'Corona', 'Virus' or '19' in any variation, especially in that specific succession. So in an effort to avoid divine punishment, humanity made the collective decision (headed by Dan Avidan of the Game Grumps) to henceforth refer to the virus only as the 'Backstreet Boys Reunion Tour'.

Seven people in my town died after attending the Backstreet Boys reunion tour.

A sleazy, jealous, wannabe, blood-sucking, degrading, smile in your face, bitch of a soulless person who deliberately betrays someone more honest and takes advantage of people because they can't grow up and deal with their insecurities. They love talking crap about you behind your back. And they pay more attention to u when u stand up to their childish behavior.
