The tendency for mayors in large cities to spearhead a flashy, big building project (stadiums, convention centers, etc.) at the taxpayer's expense, and often with rushed planning. Mostly motivated by wanting to out-do the previous mayor, it often is seen by most as misplacing funds that would be better invested in basic functions, like infrastructure, schools, and the like.
Chicago citizen: Our mayor would rather spend millions of our taxpayer funds on a new stadium, when he can't even keep the schools open.
New Orleans citizen: Clearly, our mayors are fucking us with their mayor balls. We can't even keep the new Superdome lights on during the Super Bowl, let alone keep the levies from breaking.
