This is my term, I've used it for years...
I cap cappers.
What do I mean? Some of that has been covered.
One part that hasn't, I'll see someone that's went through a slump for a bit, took a break and starts capping again -- instant tail.
There are so many situations like this.
Also, some guys know their home teams and how to get them. Others are just emotional.
I generally do not use this for evil -- such as fading someone.
The due factor is big here.
