@coral Recreational Anger: read things that upset you so you can feel upset, and share it so other people can be angry along with you and you feel less alone. These things needn't be true to suffice: make some up.

Habitual Disdain: hating someone because you have for a long time, attributing malfeasance to everything they do. Share "information" (truthful or not, it doesn't matter). The more shaming and blaming you put on them, the more easily you can justify your disdain.

These are the textually-transmitted diseases of social media.
