“I call bullshit.” I used to see that a lot on social media, back when I was on social media. But what does it mean? It means, “I disagree.” That’s all. The statement has no further content. But “I disagree” sounds bland and flat while “I call bullshit” — well, that sounds badass. You must have some powerful Refutation Mojo if you can call bullshit, just like that, right there on the internet in front of everybody. 

When we were kids, on some excursion in a parental automobile, and were leaving the mall or the grocery store or the McDonald’s, someone would shout “Shotgun!” And then one of the bigger kids who hadn’t said anything would calmly climb into the shotgun seat, after which a little voice from the middle of the back seat would whine, “But I called it!” — and would simply be ignored. Calling bullshit is like that.
