'Oddly Satisfying' is a term that has existed on the internet since around 2011.
And it's weird to me that we would call it 'oddly satisfying' instead of just 'satisfying.'
When objects are organized, it makes me feel like I have a handle on things.
To you this is just a protractor that fits neatly onto a round stone, to me ... it's control.
Maybe what's so odd about it is that the average person never feels that way?
