If it comes from Amazon, which I suspect it does, given a few comments to that effect, then it's because one of Amazon's 'Leadership Principles' is 'Be Frugal'.

These principles get drilled into you repeatedly, through new hire orientation, interviews, etc. In particular, you get evaluated against the principles in your annual review, so it's important to try and find ways to say that you have worked by them.

So when you look around and see everybody trying to apply 'Be Frugal' by penny-pinching on unimportant things, or refusing to buy software and thus spending hundreds of hours in dev time, it's quite natural to rephrase it as 'Being Frupid'.
