Monks, have you ever used an acronym with the assumption that everyone you're speaking to knows it. Fair warning, at least one of them probably doesn't and will try to decode it without interrupting to ask.
Earlier today I was discussing configuration options with a friend of mine, I said I planned on using Config::Tiny and just some simple ini files, but I was having trouble validating the creation of a nested structure using some user-defined sections for the nesting, so my friend suggests YAML thusly: "Why don't you use YAML?".
Now I had heard YAML before, but always as an acronym, and had guessed that it stood for Yet Another Markup Language and decided that quipping back: "You really expect me to learn Yet Another way to configure my programs?". This fetched merely a blank stare from someone who usually laughs at even worse puns.
The misunderstanding was quickly clarified, and in this case harmless, but the next time you step to use an acronym, think, "Does everyone really know what I'm saying?"
Note: For those who don't know, YAML stands for YAML Ain't Markup Language
