I read an article about biopic of Bush.
"The No Country for Old Men star also reveals that he broke out in acne from the stress of trying to learn all of Bush's ticks and mannerisms in time to shoot the film, which has been hurried into cinemas in order to debut in time for the US presidential election."
What is 'tick'? I looked up the dictionary, but I don't understand its meaning.
Because it should be spelled "tic"
