People Can Be So . . .

Some people think they are so great. I am trying to come up with just the right word to describe the behavior of certain people on Facebook. You know the type--the females post an explosion of photos of themselves in different outfits, and the males post an eruption of pictures of themselves in different situations, drinking beer. And just like television, an incredible technological advancement with limitless potential has been debased by the masses and used as a conduit of dishonesty, preening, pimping, hijinks and tomfoolery. The word does not exist and needs to be invented. Some candidates:
1. putreficacious
2. grosseating
3. nausifying
4. sillisocious
