Jerk

Anna was walking with the boys and tuned into a game of tag they were playing. She noticed that it sounded like Anders was saying the word "jerk" every time Kuba would try to tag him and then would duck away from him. Anna asked Anders what he was saying and Anders confirmed that he was saying the word jerk. Anna went on to say that it wasn't a very nice word and was about to explain when Anders asked "Why - I'm just trying to jerk away from Kuba?" A good example of a 6 year old interpretation of the word jerk. I am imagining he heard this on the school playground and found a way to make sense of it.
