Z-badge - the perhaps unfair branding and discrimination of people in social media as shallow who overuse "z" instead of "s" for either overzealous panache, unwise street cred or lack of mindfulness to grammar rules, likely deserved but superficial profiling nonetheless
Facebook Limbo - the inability to complete any task in Windows because a Facebook instant message is stuck sending to its intended recipient

Heavenly Hashtags - the creative use of hashtags (those things preceded by a #) i.e. #iwasateenageleroyfromFame #theanswerisalways43 #turkeyscanfly #ifnakedatworkiswrong
Personal brand still in boxes - the appearance of a new member to a social network with no profile picture, friends, posts or information - as when a person just moves into a house and has all furniture still in boxes a month alter

SlothReturns - the response to a friend who wants you to attend event/make a contribution/write a post or some other item requiring action, with a reply that expends the least amount of energy possible yet acknowledges receipt of message - i.e. "congrats XoXo" , on Facebook commonly the "like this" function for updates
Jay Leno-ing - in social media terms, somebody who has way to much exposure for their own talent, not necessarily funny or insightful but remains in the public eye based on friend's support and establishment credibility @aplusk rings a bell
RonPauled - the initial fast growth of your community to 100 members in the hopes of going to 1 million only to be stuck at 253 three months later, named after libertarian Republican candidate for President in 2009
Sajaking - somebody who is oversyndicating their content on way too many networks, polluting the web with the same boring stuff - named after the host Pat Sajak, host of the most syndicated show on TV Wheel of Fortune
