FIFO is an abbreviation with multiple meanings depending on the context. It’s most commonly known in business, tech, and casual texting culture, but the way you interpret it depends on where you see it.

   • Example: In a bakery, the bread baked first is sold first to prevent it from going stale. This is classic FIFO in action.
2. Funny Internet/Friend Opinion (Informal Texting Use) – In online chats or forums, some users creatively repurpose FIFO as slang, like “Friend In, Friend Out” or humorous takes depending on the conversation. These are context-driven and usually informal.
