phrase coined by John Lowell for moderately attractive female artist who becomes the most beautiful woman in the world the second she opens her mouth
Stevie Nicks displayed "The Sinead Effect" during "The Dance" tour in 1997.

Belinda Carlisle and Susanna Hoffs are definitely not "The Sinead Effect" (being hot and slutty in the 80s is an automatic disqualification).
