Covid

--Verb--
The term "Covid" should be implemented when speaking of a person/situation that gets out of hand quickly and with little or no cause (ramping up 0-90 in 3 seconds flat).

This term implies how quickly the Covid-19 virus went from its origin to worldwide pandemic in days.

"One second he seemed calm, the next he went all Covid on them."
"You get my brother talking politics and he will go Covid on it."
