humblebragger
A person who often posts gifts, meals, and vacation vistas on social media. Includes very beautiful tablescapes and flower arrangements. Tries to distance these from bragging by explaining recent hard work, travel hardships, or other obstacles that almost prevent the post from happening.
The Golden Child is quite a humblebragger. She will do doubt post some wedding photos with the caption "after 8 months of planning we are finally here to say "I do!".
