This often happens in sports but in everyday life as well.
Say, in a football match, player A accidentally makes player B of the opposite team fall lightly. That is a very small fault but B screams like crazy as if he hurts a lot. But actually, he is faking his hurt with a purpose of letting the referee book player A a red card or send A out.
In everyday life, you rush and by accident bump into a man, which causes a very small scratch on his leg. He then starts to scream loudly and asks you to pay a lot of money to him for that very small incident.
In everyday English, how to express the action that a person forces you compensate a lot for your very small bad effect on him?
Maybe, the man is tricking me into his exaggerated schema.
