It looks like this guy plays air drums to desperately escape Meghan's touch.
This is the most revealing Meghan cringe because it was two years before meeting Harry and world wide fame, showing that these behaviours have been ingrained for a long time.
The rumoured back story here is that Meghan forced her way into the USO Holiday tour 2014, which is a tour that goes to USA military bases around the world entertaining them for Christmas. In doing so, Meghan replaced a popular and talented actress, making her unpopular with the rest of the cast.
It’s fascinating, it’s like she glitches and doesn’t know how to gracefully escape social humiliation if that conflicts with her compulsion to be front and centre.
After being rejected by her coworkers, she should have tucked herself behind the group on the left, and just sung and danced along supporting the singers, allowing the spotlight to be on them. She could have pretended the coworkers were engrossed and didn’t notice her, and the cringe would have only lasted a few seconds.
Instead she stood there, painfully awkward in the dead centre, and did her usual trick of air-talking to the person ignoring her to pretend they are having a conversation together (when she did the drumming motion too like she’s in on a joke). It took her ages to start mouthing the words and she looked like she wanted the ground to swallow her up.
Despite the agony and the complete pointlessness of her unwelcome presence on stage, she just couldn’t bring herself to step out of the spotlight. Even at the end of the song, the way she gestured to the actual singers drew more attention to herself.
There must have been more going on behind the scenes to make the other cast members hate her this much that no one rescued her, despite it affecting the whole performance. She could have just pretended it was her agent’s fault for replacing this other actress. I bet she was an utter cunt and nobody could bear to interact with her.
