Profanity is a language all programmers speak fluently. Coding can be frustrating, which is manifested in some commit messages for Git and other version control systems. Warn your co-workers, if you tend to curse or swear in commit messages.
This design shows a yellow caution sign with the warning "I CURSE WHEN I COMMIT CODE". Great for work, code sprints, conferences and other events for programming geeks & nerds. Also a funny not-so-subtle gift for your cursing coder peers.
