She sat in her customary seat, the love seat perpendicular to the sofa that faced the television, and kept muttering as she waited for her parents, who stood in the doorway to her room chatterwauling.
From What the Shadow Told Me
A woman who will not stop her inane 24/7 chattering except when you are nailing her like shingles to a roof.
Me: Sweet Jesus, my balls hurt!
Dave: What happened, or do I want to know?
Me: Elida will not STFU for 5 seconds about her daily activities! Who cares who used sugar in their coffee at work! The only way to make her stop is when I am riding her until she bleeds! My god! I had to do it 6 times last night just to get some sleep! What a fucking chatterpus!
Chatteral-damage is a combination of collatteral, chatter and damage.
Concept is that chatterall-damage is caused when a group(s) of uninformed people chatter and gossip about things they cannot verify and know little about. This causes damage in the groupthink, damages affected persons and slows down the process of actually establishing what is going on in the first place.
Acknowledgement to Mr Flower who expressed this concept to a group of people I was in, September 2010
