A theodorian is someone who makes the claim in which Theodore is receiving the best head among the 3 chipmunks. Despite the many adversities including verbal abuse from normie alvinists, and general ignorance throughout the chipmunist community, the theodorians still are able to stand their ground as valid theorists. This is likely because the theodorian theory disregards unimportant factors such as
attractiveness and popularity of the female chipmunks (both of which have been proven to be unrelated to the enjoyment of one's head), and instead takes note of the more complex evidential reasons.
The theodorian theory, at its heart, takes into account the level of each chipmunks sexual stimulus. Using this method, we can make the assumption that because Alvin is the most popular and alpha of the 3 chipmunks, he has likely already received head
multiple times. Theodore, on the other hand, is most likely
getting head for the very first time, and it is commonly assumed that he has not even masturbateed before. If these
assumptions are true, then Theodore, at the time of the picture, had never had an orgasm before in his life. He then, conclusively, would have by far the highest sexual stimulus of the 3 chipmunks.
