Richie Tozier

dubbed "Trashmouth" by the Losers due to his foul language and loud mouth that often got him into trouble. He hated wearing the glasses, but found comfort in that one of his idols, Buddy Holly, was famous and also wore thick glasses. The other Losers often used the phrase "Beep-beep" whenever they needed to silence him. Although Richie misbehaved a lot in school, he received good grades besides the grades in behavior. At some point in the book, Richie accidentally insults Henry Bowers and his gang out loud, resulting in him getting chased and almost beaten.

Richie is known for his hobby of doing voices and impersonations, although when he is younger most of them were awful and sounded the same

Richie is shown to have had a positive upbringing, knowing how to read his parents like 'well-worn and well-loved' books. Richie's father, Wentworth, was an intelligent man with a career in dentistry who would happily indulge Richie's interest in 'voices', even using some of his son's phrases himself. While Richie's father did regard his son as a little silly, it's made clear he cares about him and loves him dearly. Richie's mother, Maggie, was kind and attempted to understand her son, but experienced some difficulty due to Richie's gender. She goes so far as to wish Richie had been born a girl so he would be able to better understand some of the things he does, demonstrating her desire to be a good mother to him. While Richie's parents may falter on occasion, they are nowhere near as severe as the other parents of Derry, who demonstrate great abuse and neglect toward their children (i.e., Eddie's overbearing, isolating, and manipulative mother, Bill's negligent parents, Beverly's perverted father and so on).

One of Richie’s greatest fears, other than clowns and the teenage werewolf, seems to be going missing (i.e., the missing poster). It was already proven earlier the children of Derry were forgotten weeks (or possibly days) after they disappear, and he seems to fear he, too, will be forgotten if he were to go missing, though he could simply be afraid of the implications that going missing meant he would die. It could also be inferred that Richie is mainly afraid of people finding out about his sexuality, using the clown or teenage werewolf metaphors. In the novel and miniseries, Richie is afraid of the teenage werewolf from the movie he and his friends watch at the movies. A comparison can be made between the teenage werewolf and Richie’s hidden sexuality. In the 2017 adaptation, Richie has a fear of clowns. A comparison can be made between the makeup or mask that clowns wear and the mask that Richie puts on to hide his sexuality.
