The Pope actually initiated a crusade against Catharism, I think it was the only Christian on Christian crusade, but they don't like to talk about that one because it doesn't fit the narrative. Regardless, the Catholic Church is evil.

Doesn't really have to do much with your post, just same Greek root word.

Last time I did meth I drank too much and couldn't piss. Cousin Jeff took me to the hospital for a catheter

Champagne and other sparkling bottles are often made with a thin metal cage around the cork to prevent the pressure inside the bottle pushing up against the cork and making the bottles explode. Human emotions are similar to the pressure which can build up in a bottle, except we don't have the metal cage to indefinitely stop us from exploding, and eventually, with too much pressure and not enough release, the human mind will either explode, implode, or go rotten.

It's important to release pressure in the mind, especially for men who are hardy or solitary. Catharsis doesn't necessecarily require another person to be present to hear the expression, only that the expression is made. Talking or even arguing with yourself, screaming in the woods or into your helmet on your motorbike on the highway are forms of catharsis.

The etymology is that it is from the greek kathairein, which literally means to purge or empty -- as in, your bowels. The original catharsis was that wonderful feeling you have when you just finished a huge shit.
