There is a common figure of speech "to be looking for trouble". It means that someone is doing something that can result in difficulty, or danger, or unpleasant consequences.
At a sporting event, a person who sits with one team's supporters while cheering for the opposing team is looking for trouble.
Mary, you are late every day. If you keep this up, you will be looking for trouble.
If a person is told "you are looking for trouble" and replies "I do not look for trouble, trouble finds me on its own", what he means is that he is not intentionally doing anything that may reasonably be expected to provoke the bad results.
