"Angles and dangles" is a submariner's term for surfacing and submerging repeatedly or it can be used for substantial changes of depth underwater. Used to train the crew.

The down and up angle of the sub as it does this accounts for the term. The "dangle: part is thrown in because submariners are the greatest miltiary men in the world, kind of like supermen.

And when bubbleheads screw up and scrape the bottom while performing said maneuver, its known as "tripping over your own ****" :)
