The paper discusses the notion of onomastic inclusion and exclusion of teenagers in their everyday life. The socio-onomastic site is a Swedish mediumsized town, Halmstad, which is somewhat segregated. This indirectly affects youngsters. In the study, two layers are studied – the geographical and the virtual environments. The first component study describes the geographical environment based on commercial signs around four different squares. The results show that in the center English appears on signs as often as Swedish do, while Swedish is preferred in the middle class areas and Arabic sometimes exists around the square where many Arabic speakers live. The second component study describes teenagers’ created usernames for everyday interaction in social media through their mobile phones. The results show close links to offline personal names, and that teenagers create new kinds of social hierarchies and draws on resources from a variety of languages.
