The expression "horn in" means to join a conversation or situation without being invited or without permission. It is often used when someone is interfering with something that they shouldn't be involved in. For example, if two friends are talking and a third person comes up and starts talking and interrupting without being asked, they are "horning in" on their conversation. It is considered rude to "horn in" unless you have been invited or given permission to join the conversation or situation.
