abbrev. Ashley Simpson Syndrome

a condition caused by the unwarranted promotion of a talentless, tasteless, or otherwise unworthy person, event, location, or other. Popularized by the insane amount of promotion given to Ashley Simpson despite the fact that nobody liked her or her music. Phrase was originally coined on "Riding with the window down..." podcast - June 12, 2006.
After seeing that the reviews and reality of the new blockbuster were not at all the same, he chalked it up to another case of A.S.S.

Ashley Simpson Syndrome has caused countless cases of buyer's remorse whenever someone believes the hype and buys an album, DVD, etc.
