Sludgebrain
An emotionally-stunted kind of person, the type to exclusively respond to everything with "wholesome", "valid", "oof", "mood", or "poggers" and nothing else, as if his or her brain has rotted into sludge. Sludgebrains are typically only found on the internet, and are extremely rare in the real world. A typical sludgebrain will usually have pronouns in his or her bio and a religious obsession with Animal Crossing or some shit.
