This study examines the types of swear-words and the social factors influencing their use by Karen’s Diner’s servers, utilizing Battistella (2005) categorization of swear-word types and Holmes (2013) theory of social factors. This study used a qualitative method to analyze 29 Karen’s Diner’s servers’ utterances, collected from the company’s Instagram Reels posted between June 2023 and May 2024. Six swear-words were identified; they are: shit, fucking, dickhead, fuck, bitch, and shitty; with fuck and fucking being the most frequently used term. The findings of this study shows that obscenity is the most frequently used type, followed by vulgarity and epithets, and no cases of profanity. Analysis of the social factors revealed that most of the swear-words uttered were used in personal topics and served affective functions, implying that the swearing was intended to express emotion dominant sub-variables and entertain customers. In conclusion, the deliberate use of swear-words by Karen’s Diner’s servers supports the restaurant brand marketing strategy, where taboo and offensive language is utilized to entertain and interact with customers.
