"Shrug Life" - ¯\_(ツ)_/¯ (emoticon by Stewart McKinney) - This term came about as an extension of the "Kanye Shrug", a term used in hip-hop circles to indicate that there was no more that could be said on a topic, or there is no reply. It can be used almost interchangeably with Kanye Shrug, but has the advantage of being not as well known initially, and a meta-like slangification of an existing slang term. Usage:
Person A: "I can't believe it!" Person B: "What?" Person A: "Duck Dynasty starts aren't even real rednecks, they've made the show up!" Person B: "Sorry to say, but most of what's on Reality TV ain'treal." Person A: "But I was #teamduckdynasty! How could they do this to me?" Person B: "#shruglife (¯\_(ツ)_/¯)"
"Creative Commons" - I came up with this term to indicate in response to "Can I use that?", which is part praise, part request which comes after something particularly witty is said. This refers to the Creative Commons set of licenses which allows one, to paraphrase from the Creative Commons page, "want to encourage readers to re-publish your slang, as long as they give you credit".
Person B: "#shruglife (¯\_(ツ)_/¯)" Person A: "Oh man, mind if I rock that?" Person B: "It's Creative Commons, man, just spell my name right."
