IN BRIEF: Something that kills the chances of a good outcome. This is mainly said when competition is involved.
IN BASKETBALL:
-A completed buzzer-beater at the end of
the game to take the lead,
-a field goal or free throw made for a team with just enough time for the opposite team to not produce the
win or
-if the lead is completely out of reach, "2:00 left" is automatically the dagger.
IN
FOOTBALL:
-A completed touchdown, field-goal or a safety at the end of
the game to take the lead,
-a touchdown, field goal or safety made for a team with just enough time for the opposite team to not produce the win or
-if the lead is completely out of reach, "2:00 left" is automatically the dagger.
EXAMPLE: Mo Williams
shot the dagger in Cleveland's win against Atlanta in
Game 4. Just so you know, Cleveland swept Atlanta in that
game, too.
