Something that's unprovoked is done for no good reason, with no real cause. A slap across your face is unprovoked if you did nothing to make the slapper mad at you.

President Franklin D. Roosevelt famously described the 1941 attack on Pearl Harbor by the Japanese, which brought the US into World War II, as "unprovoked and dastardly." A military action that isn't reacting against a previous attack is unprovoked, and a furious outburst from your friend is also unprovoked if you gave him no reason to be angry. Unprovoked comes from the verb provoke, to deliberately incite anger or annoyance in someone. The Latin root is provocare, "call forth or challenge."
