This is a thing that is recent to my awareness. Apparently people come home from work, or from something else involving having to leave the house and thus have to wear pants/trousers, and they take them off in order to signify and/or reach a relaxed state. They also like to proclaim this in the form of a facebook status, tumblr update, and/or tweet on twitter.
It does not matter what their gender is. Man, woman, or whatever they see themselves as, they come home and they take off their pants/trousers and announce it to the Internet in some fashion.
Since when was this a thing? Did people always do this and I just never noticed/found out? Do YOU do it?
Personally, I'd find it really odd to be walking around my house without some kind of pants on. But what do I know?
