This document discusses the development of a new vocabulary among American gay men, particularly terms used online to indicate sexual preferences and HIV status when seeking partners. Key terms that have emerged include "barebacking" for unprotected anal sex, "poz" to indicate being HIV positive, and "DDF" meaning "drug and disease free". The rise of these terms is linked to the practice of "serosorting" where men seek partners of the same HIV status. The document explores how the internet has facilitated the development and sharing of this new vocabulary by making partner seeking easier and more anonymous.
