To follow someone on Twitter is to subscribe to their tweets in your timeline. Following others is a great way to connect with them and to keep up-to-date with what they do as their tweets will automatically show up in your own timeline. On Twitter, you can choose to follow anyone. When you follow someone, you are called a follower of that user. To stop following another Twitter user is to unfollow them. Once you do this, their tweets no longer show up in your timeline.
