After witnessing the crucifixion of Christ and the phenomena accompanying it the witnesses are said to have smote their breasts and went away.
KJV Luke 23 : 48
And all the people that came together to that sight, beholding the things which were done, smote their breasts, and returned.
It's not clear what their action signified here whether it was triumph/victory or shame
In one other incident where a similar incident took place is in the parable of the Pharisee and publican in Luke 18.In this particular incident it signified shame.
KJV Luke 18 : 13
And the publican, standing afar off, would not lift up so much as his eyes unto heaven, but smote upon his breast, saying, God be merciful to me a sinner.
Usually to smote one's breast either signified triumph/victory or shame
What did it signify here?
