Internet trolling

Internet trolling is when someone says or does something online with the goal of getting a reaction from other people. It's like when you make silly faces at your brother or sister just to see how they'll react. Trolls might say mean things, post silly pictures, or purposely start arguments just for fun. It's not very nice, and it can hurt people's feelings, so it's important to be kind online just like you would be in real life.
