commbitcherate 

kuh-bit-che-reyt - or sounds like Kum-Bitch-erate
- to feel or express shared whining in excess; when two or more people get together to complain/whine/bitch about a person or situation that they have little to no control over, yet for some unknown reason thing this action will actually fix the items being complained/whined/bitched about.

Over a couple bottles of wine they commbitcherated about how no one likes their drunk asses.

Extremely negative commiserating between two individuals

The other mom and I were combitcherating over the school fundraiser on Facebook.
