At online internet newsgroups, members who self-identify as Giftgivers and Bugchasers post messages describing exchanging HIV as a gift, as the Gift. Using the literature on the social function of gift exchanges, this paper considers how Giftgiver and Bugchaser messages mobilize the language of gifts. In doing so, newsgroup members generate an ontological narrative wherein HIV, as the Gift, promotes social bonds, the creation and maintenance of self identity and social roles, and the meeting of particular goals. Thus the Gift appears to fulfill (at least discursively) many of the social functions of gift exchanges as described in the literature. Online newsgroups function as fora for the expression of a contrarian, transgressive HIV/AIDS narrative and act as 'carnivalesque' spaces in which normative social roles and meaning are inverted in the establishment of a realm whereby HIV becomes a gift.
