Pronunciation: /ˈɒs.ɪ.zəm/

Definition:
When people get judged or teased because of the operating system they use—Linux users usually take the worst of it. Happens in offices, online communities, and gaming groups when OS pride turns into bias.
Examples:
- Everyone at the office uses Windows, so I get weird looks when I boot up Linux. Total ossism.
- Trying to run my favorite game on Linux? Good luck, classic ossism.
