Flashbooking 

A mash-up of "flashback" and "Facebooking." Occurs when a friend likes/comments on an embarrassing Facebook status or photo from many years ago, causing it to go to everyone's newsfeed, thus making the person ashamed of their stupidity/awful haircut/mirror selfie.

Erica was Flashbooking last night and got me good. I forgot I still had those selfie's from high school bandcamp on my Facebook.

Flashmob 

A flashmob is when a large group of people suddenly come together and perform some sort of action, which draws an audience very quickly. After they perform the stunt, the group of people quickly disperse.

Shay Carl, Kassem G, Lisanova, hiimrawn, mysteryguitarman, denisevlogs, and other people came together at the Planet Hollywood Resort and Casino to perform a huge flashmob. It is one of the best flashmobs on YouTube. The video is called "PHAMOUS PLANET HOLLYWOOD FLASH MOB!", uploaded on ShayCarl's channel.
