Walking Petri Dish 

Someone who has had sex with so many people that they are virtually guaranteed to have multiple STD's. Similar to a walking STD.

Me: "Pat and John are walking petri dishes."

Jane: "I know, they're total male sluts."

Walking Petri Dish 

Someone who gets the Covid-19 vaccine.

According to genetic research, the number of genetic variants of the Sars-Cov-2 virus has increased from eight possible variants before the vaccine started to be administered in December 2020 to over 400,000,000 possible genetic variants by August 2021. This information is not relayed to the public, but is easily obtainable by the general public.

The variants are mutating in the bodies of vaccinated patients as the Sars-Cov-2 virus seeks to mutate and overcome the artificial antibody resistance in its hosts. This has huge health ramifications for all people as no amount to research will be able to keep pace with effective treatments. The worst is yet to come.

Richard is fucked. He got the Moderna vaccine and a booster. He's a Walking Petri Dish now and is proliferating the unstoppable spread of Covid-19 in the name of short term convenience. Fuck him, I'm heading to my bunker with my Ivermectin.
