halitosis

Very bad breath that smells like somebody didn't brush their teeth their whole lives or use mouthwash or something. The common stench of anime/cosplay/Linux/hacker conventions, which usually mingles with the stench of the unwashed bodies of the geeks who attend them, all to produce a deadly vapor that can be smelled from up to two blocks away.

I smell halitosis in the air. A large groups of geeks are gathered nearby.
