They're just uncreative and frivolous. For example, a fill-in meme of Oggy from Oggy and the Cockroaches disliking Unikitty and liking Vitamin Connection replaced with a ruined fill-in meme of Luigi filling up the "insert media you like and dislike" spot is opinion bashing. Opinion bashing is the inabillity to handle, respect, and/or agree or disagree respectfully and/or appropriately with opinions. That is one of the reason why ruined fill-in memes are an absolute ridicule to most of the fill-in meme community.
