smile
n.— «The pattern of implied volatilities form a “smile” shape, which is called a volatility smile. Most derivatives markets exhibit persistent patterns of volatilities varying by strike…In practice, either the term “volatility smile” or “volatility skew” (or simply skew) may be used to refer to the general phenomena of volatilities varying by strike. Indeed, you may even hear of “volatility smirks” or “volatility sneers”, but such names are often as much whimsical as they are descriptive of any particular volatility pattern.» —“Volatility Skew” riskglossary.com , 2004.
