>>46275732There used to be a TV show called Lockup where they would go around to prisons in the US and interview the prisoners and ask them about life behind bars. One of the prisoners, Fleece Johnson became something of a meme due to him talking about how much he loved fucking other prisoners in the ass.
The Adult Swim cartoon The Boondocks, based on the comic strip of the same name by Aaron McGruder, had an episode in which a parody of Fleece Johnson, known as The Booty Warrior, as a one-off character.
OP's image is a recreation of said character, but edited to look like HololiveEN Vtuber Takanashi Kiara.
