This chapter explores the production of sexy 'selfies' and relationship selfies or 'relfies', to re-think 'live' gender and sexual relations in teen peer groups. It examines the theory of phallic tagging by focusing specifically on one of the rare moments of one young woman's unsolicited tagging of her cleavage to another younger boy's profile. The chapter shows how boys can insert themselves into online representations of girls without girls' consent, or can be unwilling subjects associated with girls or with girls' disembodied parts. Indicating a major technological shift from earlier articles written before the time of tagging and selfies, the authors examine how online interactions interface with offline experiences for young people, while patriarchy and sexism remain parts of youth lives. The chapter interjects with a final assemblage to dislodge and liquidate what Irigaray might call 'the mechanics of solids' in young people's digital phallocentric power plays.
