What most people don't know is that the pirate saying "shiver me timbers" actually means to "brake the boat". You see timber is obviously wood. The word shiver is to break or split, also referring to a fragment or splinter. In other words "split my wood". This term would most likely be used in an attack from another pirate ship. It does not mean the following: getting laid, an exclamation of surprise, or that you are cold. However most people do use it as an exclamation of surprise.
Come on ye Scallywags' break out yar cannon's Shiver me timbers!!
