2) "Look how superior my boring, shitty life is to your boring, shitty life" Used to passively belittle the only 250 people the individual knows.
Also used by middle aged adults mostly to post pictures of cats.

Person 2: *sees picture* "Wow, my life is pretty shitty compared to theirs."
Person 3: "I hate my job because I'm uneducated and nobody ever taught me how to work hard. I think I will tweet about it on the social media site Twitter, so maybe people will pity me."
Person 2: *reads tweet* "At least my life isn't that shitty."
