humble brag

When you want to share how fantastic your life is but you don’t want to be that person who brags about how fantastic you are, that’s when a humble brag comes into play.

It's a brag with a mild dose of modesty or even self-deprecation, so it seems like your intent wasn’t to gloat, even though it obviously was.  For example: “I have so much packing to do before my flight to Paris. Ugh, FML it's all so complicated.”
