If someone said, “You throw like a girl,” or, “You run like a girl”? Would they be insulting you?

Do you think society sees it that way? It is a powerless thing to imply about someone. When did it start to be a bad thing to do something like a girl?

I found this video really moving. The phrase "like a girl" is full of assumptions that girls can't do things or can't do things the 'right'. Forget that. Do things #likeagirl!
