On fleek. Yolo. Bae. Basic. Winning. All frightfully au courant slang words that should make any man over the age of 25 cringe to read and bellow with rage if a chum were to utter them in jest. Using such words is the equivalent of a drunken uncle dancing at a wedding, David Bowie experimenting with drum 'n' bass (why David?) or Sylvester Stallone outrunning an explosion.
