What is a tagline?

A tagline is an often repeated phrase associated with an individual, organization, or commercial product; a slogan. It's a marketing/branding term. Examples are "Melts in your mouth, not in your hands" (M&M Candies) and "Just do it" (Nike). Taglines are also associated with movie and TV characters (The Terminator: "I'll be back.") and with movies themselves (Alien: In space no one can hear you scream.).

I believe everyone should have a tagline. It can be dramatic, mysterious, playful, profound, or sexy. Just so it sums up some aspect of your otherwise indefinable character.

What's yours?
