"10 things I hate about you" is a great 90's movie about appearances can be deceiving. It's about a girl who refuses to "go along with the flow" and fights society. She falls in love with a boy who turns out to be only dating her for money. She seems really mean but s in fact nice.
It means to give credit to the author and source. It helps in an argument because when you're trying to prove a point, you have to have factual evidence that proves you're right.
