YouTube is the go-to place now for learning anything and while some use it for picking up cooking or other domestic tips others use it for a little more violent something. Actress Amanda Cerny is one of the most popular social media influencers who has a massive 35 million followers across facebook, YouTube and Instagram and she regularly posts videos and pics of her private lives that keep them all super happy.

Amanda's latest post sees her and boyfriend Johannes Bartl cozying in bed when she watches a karate video on YouTube and pulls him into moves. The seemingly stronger Bartl who is also a social media star in his own right has her in a deadlock and she feigns surrender.

At the most unexpected moment Amanda attacks Johannes below the belt and hurts him but has added in her caption "Fun fact - I’m a black belt". Well hopefully all is well with the young man who got it where it hurts most.
