1. Being the victim of something. Not something terrible, just something they can really milk for sympathy, or special treatment, etc.
2. Being Disenfranchised (why would you like that?)
3. Feeling like they stuck it to someone (we suck)
4. Something terrible happening that they can blame on someone else
5. Catching someone else in a lie
6. Gruesome murder stories, especially if true
7. Protesting stuff. Just in general.
8. Having a posse
9. Being Morally Superior (but NEVER judgmental!)
