Invitation Party

A party hosted by HIV+ individuals with the intention of infecting other individuals with the virus. These parties are usually attended by individuals who feel as though contracting the virus is inevitable, so they might as well get it now.

"What are you doing Saturday night?"
"I'm going to an invitation party."
"What? Make sure to use a condom!"
"No man, I'm gonna get HIV anyways, might as well do it now."
