smartghosting is when in a chat group you write to someone (eg. with a @Carl) and that person not only ignores you but instead he write something else to someone else.
Joe: "Hey @Carl, can i have a feed about that?"
Carl: "@Mark, can you please send me a report? @Jerry, you can proceed with your activity. Thank you all"
SmartphisticatedWhen someone has the perfect blend of brains and class — smart and sophisticated. They’re quick-witted enough to solve problems, stylish enough to turn heads, and confident enough to do both at the same time. Basically, the person who can quote Einstein and order the right wine.
