What Hand Sign Did Prince Harry Just Make?

When Prince Harry met with Melania Trump, many noticed how his hands were positioned inside his blazer, and some say he was calling her the devil. There is a strange conspiracy theory going around online, suggesting the prince's pose could have been a devil horn gesture. "When Prince Harry is trying to tell you something by flashing the sign of the devil," read one tweet. In the photo taken over the weekend, his hand was half-tucked into his jacket, with his pinky and index fingers sticking out.
