This paper presents an analysis of the use of humorous stickers within a WhatsApp chat group. With the rapid growth of digital communication, particularly on mobile devices, WhatsApp has become a popular platform for various forms of interaction, including voice and video calls, as well as text and voice messaging. In this context, humour is a prevalent phenomenon, especially in groups where participants have established familiarity and trust. The prevalence of humour in digital communication is largely attributed to the use of multimodal resources, such as stickers – digital images that can include text and are used to convey emotions, feelings, and humour. The study’s initial hypothesis posits that stickers serve as a means of humour contextualization, helping to emphasize and enhance the intended humour in messages. Additionally, stickers are believed to aid in reducing misunderstandings during communication and mitigating potential threats to the participants’ social image. For this case study, the researchers employed a qualitative approach to analyse conversations within a Spanish WhatsApp group comprising numerous participants, resulting in a corpus comprising 44,362 words and 273 stickers. From this data, they selected 8 humorous conversational sequences that exemplify the primary uses and functions of stickers in this digital context.
