A nipple, breast, or hill, depending on your location, mood, and distance from the target zone.
(Perspective surely comes into play here, not?)
Another one of those Gaelic terms which has the power to give new meaning to the old expression "to breast a hill".
Only it's not a new meaning. It's old as dirt, which is what hills are made of.
Luck or coincidence? No one alive knows the true answer.
