Assembling Ikea furniture is easy in the sense that most people can do it eventually, but it's kind of tedious, easy to make an annoying mistake that requires backtracking and often stressful. People elsewhere in the thread mentioned assembling it with kids around, and often you're putting it together at a hectic time because you've just moved or need the furniture ready and the house clean before having guests, etc. Enough people have had these experiences that the meme is popular. I don't personally care for mayonnaise. I think the memes are popular precisely because mayonnaise is so popular. A lot of the anti-mayo memes I've seen complaining about mayonnaise are about finding it where you don't expect it or ordering sandwiches without it and still getting it. There are fewer memes ranting about less common ingredients like Buffalo sauce or hummus because you don't have to go out of your way to avoid those.
