auger

A drilling tool that bores holes into wood, ice, or earth using a helical screw blade, like a corkscrew with ambition. Carpenters use small ones for precise holes, while landscapers deploy massive versions to drill fence post holes or tap maple trees.

code

The arcane text that developers write to make computers do things, composed of strict syntax that will break if you miss a single semicolon. It's simultaneously the most logical and most frustrating thing humans have ever created. Also refers to laws, secret messages, and moral standards, but in tech circles, it's always about those sweet, sweet lines of JavaScript that definitely don't have any bugs.
