In ballroom dancing, the leader is the person (typically the man) who directs the follower in the steps they take on the dance floor. A good leader is sometimes a difficult find, because new dancers typically think that new steps are the only thing worth knowing, and consequently are more popular with the ladies. This is a good thing.

First they haven't used lead in pencils in years. Many many years. Due to the possibilty of lead posioning. They are all graphite now.

Second a story about lead. When i was young me and my grandfather used to make our own fishing weight by melting lead and pouring it in molds. We used to do this inside in his not very ventilated kitchen. When lead is boiling i any water gets in it the water boils instantly quickly expanding causing the boiling lead to explode. My mom walked in the kitchen and got a drink and as she was walking out of the room dropped the cup. The cup landed on edge shooting a small stream of water into the air. Me and my granfather dove on the ground and covered our heads and then... BOOM. When we finally got up the entire kitchen was covered in a coating of lead. It was every where. The cabinets, the table, the floor, us. Everything was covered inb lead. The best part though was the lead stalagmite that now hung from the cieling over the stove. It took a good five or six hours to remove all the lead from the room and from then on we had to make weights outside.

DISCLAIMER: Ok, here's the thing, please don't fucking do this. This is a bad idea.

Verb: to lead, as in to point a ranged weapon, with the exception of an actual laser, into the estimated path of one's target (instead of actually at the target), so that the projectile's time to target will not cause it to miss. Gamers do a lot of this when they play combat sims like X-wing and the Jane's flight sims.

In the context of a card game, the person on lead plays the first card to a trick. The choice of lead at the beginning of the game my rotate in turn or be decided by criteria specific to the game. For the rest of the time, the person who wins a trick is usually the one who leads the next one.

In oceanography the lead can be two different but related things:

By one definition it is the narrow strip of ice-free water at the edge of a glacier or ice shelf, between the ice mass proper and the surrounding sea ice. Ice masses, due to their inclination and the temperature difference between their surface and the water, often cause persistent katabatic winds that drive the loose ice fragments nearest the edge of the ice mass further out, leaving a strip of virtually clear water. On satellite images this is what gives those features a dark edge.

It is also the name (as Webster briefly states) for a navigable passage or a fracture in the ice that can be used by surface vessels, whether it be open or frozen over again little enough to be broken.
