1. To hurl, toss, or throw something at someone or something. We sat there pitching balls of paper at his desk to get his attention. He was arrested for pitching rocks at people from the overpass.

2. To set up some kind of temporary living arrangement at some location. We always pitch our camp at same spot by the lake. We were about to pitch our tent at the campsite when a huge storm started blowing away all our equipment.

3. To propose something in a particular setting or place. They let me pitch a few ideas at the board meeting, but I don't know if the directors liked any of them. She pitched a radical new kind of cybersecurity software at the convention.

4. To target something, especially advertisements, at a particular demographic. It just sickens me how these companies shamelessly pitch ads at children at such a young age. It's still really weird to me how websites pitch advertisements at me for things I write about in emails and blog posts.
