Flashbanged

When you hear someone say something that's so out of pocket, your body ceases to function and your brain experiences a factory reset, similar to that of being subjected to a flashbang.

"I'm not okay man, Steve just flashbanged me mid-conversation."

Facebook Flashmob

In a collective effort, facebook friends of one person steal and adopt his/her profile picture, and each tag the original owner in their new pic. Then the group then likes and comments on everyone's new profile pic, ensuring a barrage of notifications for the target person. Works much better if the adopted picture is in any way scandalous.

Last night while Matt was out to dinner with his parents, 10 of us got him with a facebook flashmob. His phone must have buzzed non stop with notifications!
