noun

scupper

An opening that lets water drain from a ship or building.

Rainwater flows through the scupper and away from the roof.

Etymology

The drainage opening has an uncertain deeper history. Its established function is to let accumulated water pass out, rather than naming the act of deliberately sinking a vessel.
