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.

Backstreet 

Coming from the wrong side of the tracks, poor and uneducated, from a low socioeconomic group. This term (backstreet boy/girl) was around long before the band of the same name.

I'll go out with him. My dad'll kill me, but I love backstreet boys.
