How to assert dominance over your lane

Spam your mastery. This will scare the enemy and make them play poorly. Give them first blood by diving tower. Let them know that you're not afraid of them at all, even with the lead. Keep fighting them in lane, and push them in. Give first blood tower. Explain to the enemy team that your jungler is bad, and that you'll still beat them 1v1. Beat your lane opponent 1v1, with some minor help from your teammates. Feed more kills. Lose inner tower. Trade objectives and take a jungle camp. Now you've got 100 gold, and they've got 100 gold. Before they take the inhibitor tower, surrender and deny them last hit on the nexus. Make sure you're at the end screen and dance.
