There have been some theories on this phenomenon, with the most prevalent being the tendency for Wikipedia pages to move up a "classification chain". According to this theory, the Wikipedia Manual of Style guidelines on how to write the lead section of an article recommend that articles begin by defining the topic of the article. A consequence of this style is that the first sentence of an article is almost always a definitional statement, a direct answer to the question "what is [the subject]?"
I recommend watching a youtube recap of the history of the fandom as it really helps contextualize the whole comic, and it is quite fun, as such an excentric comic attracted an equally excentric fanbase. There are plenty of fun and gross anecdotes. As for the bucket, you can watch for yourself, but let me warn you...
It's a bunch of people collectively spitting into a bucket in a restaurant
I got into it blind and only learned about the fandom and the surrounding history after finishing it. It felt like reading a parallel story and it was actually pretty fun, but it only cemented my feeling of not wanting to be associated with them. I mean, the bucket. Just wow.
That's cheating! I can take medicine with honey as well and even if it stops tasting horrible it's still the honey doing the heavy lifting. We can agree on a compromise and put honey in the D tier though.
Father and mother are probably the two worst examples. Mother is "mamá" in Spanish, and "mama" in Japanese, not because they're related, but because babies make that sound a lot.
That said, I agree with you completely. It's just that that specific example bugged me.
