Sib Sab

Taken from the words sibling and sabatical; occurs when two siblings take a break from communicating with each other because of too much time spent together or because typical sibling turmoil is wearing them out.

I'm so tired of my sister's whining and complaining about all of her personal issues. I love her, but we seriously need a sib sab for a few weeks.
