Bugchasing is a slang term for the practice of pursuing sexual intercourse with HIV infected individuals in order to contract HIV.
Some people consider bugchasing "intensely erotic" and the act of being infected as the "ultimate taboo, the most extreme sex act left."
Some contend that this behaviour stems from feelings of inevitability towards HIV among the gay community and the empowerment of choosing when to contract the virus. Others have suggested that some people who feel lonely desire the nurturing community that supports persons with AIDS.
