[Tlhingan-hol] Between us curses run like water

[mayql qunenoS]

Could someone please tell me, what this proverb actually means ? I
think it belongs in the holiday proverbs, however I can't understand
its meaning.

Does this mean that the curses we said to each other have been undone,
and we are now friends, or that because we are friends we constantly
curse each other ? Or does it mean something else ?
