Bug-chasing refers to the act of pursuing sexual encounters with individuals who are known to have a particular disease or infection. This dangerous practice is often associated with certain subcultures and considered to be a form of risky behavior. Synonyms for bug-chasing include sero-sorting, barebacking, and gift-giving. Sero-sorting is when people intentionally seek out partners who have the same infection in order to engage in unprotected sex. Barebacking is engaging in anal sex without a condom, while gift-giving is the act of intentionally transmitting an infection to a sexual partner. All of these terms refer to actions that put both partners at risk for serious health consequences and should be avoided in order to protect oneself and others.
