Living day to day with denim that you don't wash for a long time probably leads to some nasty ass stories. The type of stories where something bad happens to your jeans and you have to decide between washing and continue wearing.
Mine: Brother is a dick as always and had his pee stream mobbing all under the toilet seat. Not knowing what happened, I lifted the toilet seat with my fingers and was straight up disgusted, and out of reflex wiped my fingers on my jeans. Soaked the pee part, but I think I still smell it.
