I’m thinking that glitch at the bottom of the image is unintentional. What sort of error would it be categorized as though?

I’m unsure what the cause is, but I’ve seen it occur on Twitter images for probably multiple years now, and it’s present on the original image as shown on their site too. My only guess would be some drawing program exporting images in a way Twitter doesn’t like.
