False booking 

When you someone on FB or MS talks about how wonderful life is and always post about what a good time they are having...And then when you actually spend time with them they are just misserable....

Yvette: So how did your night out with Lisa go
Crissy: OMG!!! She looked like a lot of fun on FB, but she was totally misserable. Not sure she even knows how to be happy...
Yvette: Yeah, I've I run into a few "false bookers" myself.
Crissy: "False booking" is so misleading
Yvette: Oh look!!! her "life is AMAZING today"

farsebooking 

The act of posting on social media what a great time you're having when you're actually deeply unsatisfied, lost and empty.

Often the amount an individual emphasises how much fun their having directly correlates to how dead they feel inside. (See Tom Cruise Couch Dance Effect.)

"you're clearly farsebooking! If you were having such a good time at Glastonbury why are you even on facebook?"
