<P> Steve has a small group of friends from school that he regularly spends time with . The boys frequently engage in activities which most teenage boys have outgrown, such as slumber parties . The group includes: </P> <Ul> <Li> Snot, a teenager with curly hair, some noticeable stubble and acne, he is Steve's best friend . His character appears to be based on Booger from Revenge of the Nerds; he is even voiced by Curtis Armstrong . Snot who is Jewish, once had an affair with Steve's then - girlfriend, Gretchen . It is implied in "Roger Passes The Bar" that Snot has joined the army and turned gay, marrying his commanding officer, LT Randall Santana . </Li> <Li> Barry, a morbidly obese and apparently simple - minded boy, he has an inarticulate, strident, and sloppy vocal quality . In the episode "With Friends Like Steve's" he is revealed to be a maniacal, demonic genius made to take special "vitamins" to inhibit these evil tendencies, and cause mental retardation . Without taking the pills, he also speaks in an English accent . It is implied in "Roger Passes The Bar" that he grows up to become a gay poet working at Ithaca College, dating his male students . </Li> <Li> Toshi, a multilingual Japanese teenager . Although he seems to understand English, he has yet to speak it, with the exception of "Finances with Wolves", in which he yells "Werewolf!" in unison with Snot and Barry, and "Francine's Flashback", in which he yells "Godzilla!". When he speaks Japanese (generally with a very condescending tone), Steve believes he can understand him, though he really does not . In the season 9 episode "Independent Movie" he says "Go on without me" in Japanese, then saying "please go" in perfect English . Toshi has spoken Russian and speaks Spanish when talking on the phone to Francine (though that could be Francine ignorantly thinking Toshi's Japanese is Spanish). Though they are friends, Toshi's greatest wish is to one day kill Steve . Toshi's parents speak perfect English, as does his younger sister, Akiko, who acts as Toshi's translator in episodes such as "Weiner of Our Discontent" and "The Best Little Horror House in Langley Falls". Toshi apparently knows of Roger Smith being an alien as he once called him "that alien in the wig". It is implied in "Roger Passes The Bar", that he has moved to Kyoto, Japan to become an exotic dancer . </Li> </Ul> <Li> Snot, a teenager with curly hair, some noticeable stubble and acne, he is Steve's best friend .
