Facebook karma
When you comment on a Facebook post to trash someone, and Facebook thinks you're a drama queen and starts sending you 100 posts about the same stupid thing.
I commented 'this is the worst song ever' on a post, and now I get 100 posts about this song.
I said 'this is the dumbest movie ever' and now I get 100 posts about that movie.
I wrote 'this is the worst pizza ever' and now I get 100 posts about that pizza.
