It seems completely random. You could probably make a list 2 pages long of characters from videogames that are annoying and people want to kill. What makes Tingle, a character from Legend of Zelda, special compared to the likes of Noober or Grobnar?
More people want to kill Tingle I imagine. According to his Wikipedia page he's one of the most hated characters in video game history, except in Japan. I haven't heard of Noober but Grobnar isn't as well known. Also Fallout had tons of references that were completely random, The Flintstones, The Simpsons, They Live, one of the new Fallouts references Strapping Young Lad. A lot of these things I wouldn't have known unless I had looked it up on the wiki.
