TLA
Three-letter acronym. A dig at business language, which is full of them, and usually a hint that you've used too many. Longer ones are MLAs, multi-letter acronyms.
You'll hear it as
Sorry, there were too many TLAs in that deck.
Why it matters to you.
If you have to explain the acronym, the acronym isn't saving time.
Also called MLA.
