I searched "earphone slipping out of ear" and the first Reddit result had a troll comment as the description for the search result.

I tested the same search query on my phone, and it had the same result.
I wasn't expecting a troll comment to be used as the link description. The comment that the description uses only has one upvote and is at the bottom of the comment section. While I think it's a good idea to include a comment or the post description as the description for the URL, maybe restrict it to the top comments, or include some other form of oversight that doesn't take troll comments seriously.
