smoke-eater
n.— «Nonsmokers also had problems with the specially equipped smoking areas. Depending on the number of smokers concentrated in one area, it was rare that “smoke-eaters” as they were affectionately called, could handle a room full of people puffing away without the smoke affecting people nearby.» —“GSA gets tougher on feds’ smoking” Free Lance-Star (Fredericksburg, Maryland) Jan. 4, 2009.
