Cormacing occurs when someone's internet is so trash, that it cosmic ddos anything it comes into contact with. It is so horrible that it affects everything and everyone else using the same service, and can cause others' connection to suffer or evencrash as a result.
I was having fun with some friends last night on Xbox, until some guy joined and began cormacing the whole party.
Showing respect while driving to a unknown person for no reason other than the fact that they are driving the same car as you. Having the same make and model are key in this behavior occurring; an identical color scheme on top of these existing similarities will cause for the most immediate and conscious realization of this sudden urge of appreciation.
Example: "I gave the guy driving in front of me on the highway a 3-second space cushion because he was driving a silver civic, exactly like mine. I soon realized the only reason why I was doing this was because of Carmaraderie."
