Research in computer mediated communication and sociolinguistics, have increasingly highlighted the concept of establishing an "online identity" through specific language use. However, while emojis or common netspeak abbreviations are often the focus of research concerned with cyber language, no studies have considered the function laughter might play in establishing an online language identity. Furthermore, no studies have considered the possible significance of online laughter in terms of language acquisition. Researchers now have the opportunity to study laughter from a linguistic perspective since laughing online is illustrated through the use of emojis or typed text. The present study considers how the data and research in previous studies on written laughter and language identity can be combined to support arguments that laughing in a specific language online not only expresses the language identity of an individual, but should be considered an important aspect of second language acquisition.
