What could be a valid definition of DevOps to introduce it to a novice?

Problem
I've done / created lots of SCM related presentations, and now I'm trying to "upgrade" to a DevOps successor of it.
What I always try to do in my presentations, is to come up with an introduction slide which somehow includes the message I want to deliver (and which I then elaborate on in the rest of my presentation). When doing so, I try to answer my own question like "What would me 1 to 3 phrases be that I'd want to use if I got like 10 to 20 secs (only!) to explain it to somebody new to it?*".
I thought I knew what DevOps actually means, and what it is about. But I've seen some bizarre usages/contexts of DevOps (even on DevOps.SE ...). It makes me wonder if maybe what I think DevOps is, is completely wrong.
So what is generally agreed to be the definition of DevOps?

DevOps in a nutshell
From Wikipedia:
DevOps (a clipped compound of "software DEVelopment" and "information technology OPerationS") is a term used to refer to a set of practices that emphasize the collaboration and communication of both software developers and information technology (IT) professionals while automating the process of software delivery and infrastructure changes.
It aims at establishing a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably.

(software engineering), operations and quality assurance

While there is no single "tool" for DevOps, but rather a set of tools, also known as a DevOps toolchain:

Below are a few quotes from some of the questions on DevOps.SE, which all seem to somehow fit / confirm part of the DevOps description above:
-
From 'What is the difference between SRE and DevOps?':
... DevOps is about maintaining code ...
-
From (an answer to) 'How do I hire a good DevOps, fitting my company?':
... It is a common misbelief that “DevOps” is a role in a company. The word merely denotes an organisational shift in software companies ...
-
From 'Does my organization need adopt Agile Soft. Dev. before adopting DevOps?':
... there are still organisations which are not practicing Agile in their software development, who might be interested in adopting DevOps ...
DevOps is NOT a role
