Describe the way the person speaks and delivers speeches. What is the speaker's opinion about the person's mannerisms?
Watching this buffoonish oaf try to speak like an adult is painful. His normal speech patterns are equivalent to a nine-year old and when he reads what the adults have given him, he delivers it in an awkward, over-pronounced manner that is just embarrassing. You can just picture him after he's done, running to his handlers and asking, "Did I do it right?"
His comfort zone is delivering taunts like a nine-year old such as "Loser". He really is pathetic.
