The article deals with hybrid playful speech genres in gaming Internet communication. It briefly highlights different approaches to the definition of the concepts of “hybridization”, “hybrid”, “hybridity” which are significant for this work. The communicative space of the Internet has become a kind of genre-generating environment that contributes to the emergence of new speech genres obtained as a result of hybridization. The object of the research are humorous speech genres presented in the form of polycode texts related to congratulatory discourse (communicative events “Birthday” and “Wedding”) and which have become widespread in the Internet environment. They belong to secondary genres, arise as a result of the re-accentuation of primary genres (in most cases, institutional discourse) and are associated with the stylization process: a humorous birthday greeting, a humorous wedding telegram, a humorous family happiness formula, a humorous oath of a bride / groom, a humorous instruction on exploitation of the bride / groom, a playful wedding poster. These genres are associated with the implementation of the pragmalinguistic category of indirection, contain a language play, indirect speech acts, hints, hidden meanings. The goal of the article is to identify structural-compositional, verbal and non-verbal markers of hybridity in these units of gaming Internet communication. In addition to the humorous speech genres discussed in the article, the congratulatory Internet discourse contains “Family Constitution”, “Wedding Diploma”, “Technical passport of the bride / groom”, “Marriage Contract”, “Contract” (with father-in-law / mother-in-law), “Resolution of the Society of Bachelors” and many other genres, containing stylization of official documents. To date, such hybrid genres are still poorly studied and require a systematic analysis.
