My rule of thumb is that unless an acronym has entered the wider 
vocabulary of the general public (e.g. NASA, CIA, KGB, WW2) or is 
specific to the community you're talking to (e.g. LOL or ROFL on most web 
forums), I always treat such acronyms as niche terms that need defining 
at least the first time I use it in a thread.

Especially when, like FP and TDD, it could have multiple meanings. Did 
you mean Floating Point or Functional Programming? Top Down Development 
or Test Driven Development?

(I suppose you youngsters no longer care about the great controversy of 
the 1970s and 80s, whether Top Down or Bottom Up was better.)

No. Some jargon can exist for decades and never spread beyond a tiny 
niche, and others spread to the wider community like wildfire in a matter 
of months.

Oh, it's *easier*, that's for sure. But is it *better*? The aim of 
communication is to share information, and communication which fails to 
do so has failed.

When posting a message that aims to introduce Lettuce, which clearly is a 
niche product, it's probably not a good idea to assume that the jargon 
used within that niche is widespread.

Google has no clue what BDD is either. Googling for "define:BDD" comes up 
with four definitions:

Two for Body Dysmorphic Disorder.
One for Binary Decision Diagram.
And one for the Pennsylvania Bureau of Disability Determination.


Without the "define:" prefix, Googling finds:

The stock exchange code for DB Base Metals
Body Dysmorphic Disorder
Behaviour Driven Development
Brand Distribution and Development
BDD stairlifts
BDD Insurance

and many more. I assume the one you're talking about is Behaviour Driven 
Development. Wikipedia defines it as:

    BDD is a second-generation, outside-in, pull-based, 
    multiple-stakeholder, multiple-scale, high-automation, 
    agile methodology. It describes a cycle of interactions 
    with well-defined outputs, resulting in the delivery of 
    working, tested software that matters.

Bingo!
