was a bit of a slogan in the Anti-Onision community during the summer of 2011.
Greg uploaded the video "Shiloh Forgot Me" to his channel on June 23, 2011. In the video, he recorded Shiloh having a seizure-like episode and later losing 3 years of her memory. After Shiloh went through a lot of tears and trauma, Greg decided it was important to remind her she was a vegetarian and recorded her eating vegan cheese. (Source) To many viewers, this seemed to be a very strange priority after witnessing what Shiloh went through.
The video received tons of backlash and was soon removed by Greg.
Vegan cheese became a symbol of Greg's seemingly irrational behavior at the time.
A meme was created parodying this bizarre phenomenon called "Dr. Onision". The meme featured Greg with a Photoshopped medical mask and later versions added a stethoscope and a "Hello, my name is: Dr Onision" sticker. No matter what the illness was, he would reply with something that included vegan cheese. The short-lived meme eventually went on to include other strange medical advice Greg had given in his videos and on his social media.
