It has at least 3 meanings:

1. DevOps: A dev who can do ops and will do ops (because their employer won't hire actual operations experts)

2. DevOps: Using more development concepts and tools in operations (i.e., an operator who can do dev, but often in more of a support/deployment than product development capacity)

3. DevOps (original): A way of working that promotes collaboration, rather than separation, between development and operations (among other things).
