Someone, particularly a youtuber in this case, that puts on a cute persona that is completely different to their persona in reality.
They usually have an anime art style, a "kawaii desu" oc, and they have a small voice when they talk. (Not all uwutubers are like this, this is just an example of a stereotypical uwutuber.)
UwUf is a term used when feeling positive or negative emotions. It is mainly used in text messages or in conversation. UwUf is a compound word (oof) (UwU) and is very useful when you don’t know what to say.
“Aww man I just died in game, but I still love you” “UwUf that sucks”
(noun) the act of turning something or someone that was most definitely not adorable, cute, or wholesome into something or someone that is. stems from the slang word "uwu", which is often used to denote a smiley face with cute qualities. many fandoms have a tendency to carry out this process with regard to male villains, allowing for a deviation from canon that is met with a flourishing of art, writing, and headcanons that people forget to separate from the uwufied character's canon personality.
"Oh my gosh, Dabi is so cute!" Sally said, eyes sparkling.
"Omg, not the uwufication of Dabi!" Gertrude cried, pulling at her hair.
People suffering from uwutism are usually virgins who need to hear ara ara once in a while. I deprived of adequate ara ara, they start to get headaches and seizures and in extreme conditions, they may die.
