Facebook friendship
A Facebook friendship is when someone you don't even recognize from the back of a bus sends you a friend request, then acts like they're your bestie by liking every single stupid post you make, messaging you at 2 a. m., and poking you until you beg them to stop.
Hey, I saw your pic of pizza and I thought, 'This guy is my soulmate.'
You posted a selfie and they replied with 12 heart emojis and a question about your hair.
They poke you 10 times in one day just to say, 'Hi.'
