A perfect state of friendship. An ideal state of friendship between two pals in Serbia who call each other SIDRO. "Sidro" means an anchor, meaning the two friends provide each other with stability, comfort and support. Be a SIDRO don't be a MAČ!
Our sidrority is better than yours, damn right it's better than yours.

A very close friend who knows you inside and out and therefore has the power to cut you to the quick out of no where, catching you off guard and consequently causes you to question your very existence and doubt said friendship.
We're having a lovely conversation and out of no where she's such a zapper!
