Knudsen is the most accurate and appropriate way of describing someone who is "lit" or is yet to be "lit". Someone with the last name "Knudsen" either loves country music, or gets tortured by it every year for about one month straight. This is most likely because another Knudsen, in the nearby area, is blasting "Armarillo by morning" on their 14 year old speaker.
Neighbor's mother on a visit: WHAT'S ALL THAT NOISE?!
An anime/manga slang term for a character that is cold, blunt, cynical, and pretty much doesn't care if her beloved dies. That's what she is on the outside but she is actually caring and nice on the inside.
Differs from tsundere since tsundere is when the character frequently runs hot and cold between tsun and dere. Kuudere is when the character only occasionally shows her caring side.
Usually used in the otaku fandom as a character who is cold and closes themself from conversations or society. They usually show no emotion. Over time they open up and get out of their shell.
