i have seen all of these multiple times and i will provide examples if asked

• persons a and b are close. person a dies. person b starts tweaking out so hard they start hallucinating person a. person b has not been shown to have any mental issues that would cause something like this beforehand
• suicidal depression as comedy
• when a character is canonically evil and also german and/or involved in the military somehow... and the fan content portrays them as a nazi (if you do this you WILL be going to hell)
• when more than like 2 people are making the same facial expression in an image
• when there's a character nobody (in-universe) likes and then half the jokes involving the character are that nobody likes them
