This study explores the Swedish, non-native use of English swear words in Swedish-language comic strips. It first considers the established links between both swearing and humor, and comics and humor. It is argued that swear word usage and the comic strip framework add to a mutual feedback loop, whereby the comic strip derives its humor from the use of English swear words, while at the same time the comic strip context, by invoking a play frame, primes the swear word usage for humorous interpretation. Modeling Siegel (1995), the study then considers how a code-switch to English serves as a framing device or contextualization cue for humor in Swedish-language contexts. The inquiry of a selection of Swedish comic strips draws from the Encryption Theory of Humor (Flamson and Barrett, 2008), and proposes that humor created via the Swedish practice of swearing in English is a function of shared background knowledge that capitalizes on the basic incongruity of two discourse systems operating under distinct norms of suitability.
