9) His iconic "Purrrr" sound effect

Dustin annoyed several of his friends with his iconic purr in Stranger Things. One of the most funny yet memorable ones would be from Season 1, when Joe Keery's Steve, while dropping him at the school dance gives him a pep talk and tells him to show his lion's roar. Instead of a roar, Dustin ends up purring, making it one of the funniest scenes of Season 1.
