It stands for No Continuous Integration.
Since the check-in is gated, the existing code, plus this check-in, will be built separately and only allowed onwards if the build is successful. So when the gating process actually submits it to source control, there wouldn't be any point for that check-in to cause another (continuous integration) build to occur, since at that point thechangeset is 'known good'.
So this suffix is an instruction to the continuous integration system to the effect of: "When this changeset actually gets committed 'for real', don't automatically fire a continuous integration build on account of it".
