Facebook Hijack
You post something on Facebook and then your friends start arguing in the comments like they're in a wrestling match and you're stuck watching like you're the referee who got stuck with the worst job ever.
I post a photo of my dog and my cousin and my best friend start fighting over who has the better dog.
I post a meme and my aunt and my uncle start a 20-comment war about politics.
I post a status and my ex and my current girlfriend start a full-blown drama in the comments.
