Each character has his or her own trademark mannerism or trait. Julian often takes a leadership role and devises schemes, all while holding a Cuba Libre on the rocks in his hand. Ricky believes himself to be dumb, and his speech is often laced with malapropisms that fans call "Rickyisms"; he lives in a dilapidated 1975 Chrysler New Yorker (nicknamed "the Shitmobile"), and grows marijuana. Bubbles wears spectacles that magnify his eyes to an unusual extent, drives a go-kart, and lives in a shed with many cats; he is the least likely to face any repercussions for the trio's illegal activities. Alcoholic trailer park supervisor and ex-cop Jim Lahey usually attempts to derail the Boys' schemes, and nearly always shoehorns the word "shit" into his cautionary metaphors that fans call "Shitisms." Randy is Lahey's assistant and lover; he never wears a shirt unless he absolutely has to and is often taunted for his large gut and addiction to cheeseburgers.
