What is this simplified/less-detailed art style called?


So, recently, while watching a few of my favorite animes, I noticed this
really weird art style that pops up whenever a character will show confusion,
annoyance, etc.

Don't really know what the art style is called. Usually, they look kinda
simplified or less detailed (not sure if that's the right term). I don't think
it's _chibi_ , but whatever it is, I would like to know.




It's called "super deformed", or SD.

Some anime spin-offs of franchises in that style have the "Super Deformed" or
"SD" in the name, like "Kidou Senshi SD Gundam" or "Kamen Rider SD" others
don't, like "The Ten Little Gall Force".
