Can't Take Criticism: Somewhat ironically, John can not handle being criticized and will swiftly retaliate against any in his Youtube comments or messages in his Twitch chat with snark and removals or outright bans. He even admitted in an interview that he enjoys confronting negative comments and getting into squabbles over them.
Heartwarming Moments: During his playthrough of "Doki Doki Literature Club!", when Monika badmouths Yuri for cutting herself, John simply and calmly replies, "it just means she needs help". His general attitude of "they just need help" towards the girls in the game was noted and appreciated in the comments.
Memetic Loser: Jeff the Killer, due to a surplus of low quality games starring him and his general character just not being scary.
Red means scary, in reference to the sheer amount of indie "horror" games John plays that have an abundant amount of red. Now has a T-shirt.
Thanks to a random NPC in Outlast II, we have "Consume the flesh, spice it well."
His intro, "Hey guys, it's John!", for how simple it is, has been meme'd by his fanbase a lot as well, with the most common variation being the overdone "Hey John, it's guys!" joke. So much in fact, that John turned "guys" into an actual character for his channel, whose catchphrase is exactly that! He later murdered Guys with an axe.
