Facebook Hampster
The Facebook Hamster is the friend who lives in your feed like it's their home. They like your posts but never talk to you. They’re like a ghost who only shows up when you post something good.
You post a vacation. They like it. Then they vanish.
You post a new job. They like it. Then they forget you exist.
You post a breakup. They like it. Then they comment with a link to their own breakup.
