weeper
n.—Gloss: Related to the meaning of weeper ‘a hole or pipe in a wall to allow water to run off.’ «Six inches of rain between Friday night and Sunday afternoon proved too much for track crews. Crews fought a day-long battle with the wet track and pit road from the rain and what are called weepers. Weepers are caused by water bubbling up through cracks in the asphalt from the over-saturated ground under the paving. By 4:30 p.m., despite periods of sunshine, the plug was pulled on Sunday’s race.» —“Rain washes out Pennsylvania 500 at Long Pond until today” by Chuck Givler Express-Times (Harrisburg, Pennsylvania) Aug. 3, 2009.
