Similar to ground zero which is the site directly under the detonation of a nuclear weapon. Brown Zero is the area affected by a fart. Usually limited to a room unless the door was left open and it was really raunchy.
After I ate that big bowl of chili, my fiancee was caught at brown zero when I let one rip.
