A generic wojak
A macro meme first appeared around 2010 as a part of the "rage comics" series of memes. Originally used to display wearyness/a content mood.
Wojak saw a huge revival around 2020 as a template for various macro memes and spawned several derivatives, either as depictions of stereotypical types of Internet users or simply as reaction images.
The name is taken from the Polish word "wojak", meaning "soldier" or "fighter".
