Paranoid about the "ums" and "uhs" that pepper your presentations? Bewildered by "hella" or the meteoric rise of "so"? Can the word "dude" help people bond across social divides? Why are we always trying to make our intensifiers ever more intense? Are these language tics, habits, and developments in our speech a sign of cultural and linguistic degeneration? Fridland weaves together history, psychology, science, and laugh-out-loud anecdotes to explain why we speak the way we do today, and how that impacts what our kids may be saying tomorrow.
