Usually Black Friday sales are the ones that trigger "mall brawls."

But this year, post-Christmas sales have shoppers in a chaotic frenzy, giving a whole new meaning to the phrase "shop 'til you drop."

There were reported mall fights in at least a dozen malls Monday as shoppers sought to capitalize the day after Christmas.

Fights broke out in mall locations in Aurora, Colo., Memphis, Tenn., Fayetteville, N.C., Fort Worth, Texas, and other cities throughout the country.

In Elizabeth, N.J., video shows shoppers stampeding toward the exits after word spread of a gun being fired. A SWAT team searched the mall and found no evidence of gunfire. The sound was reportedly caused by a chair being slammed during a fight.

Despite all the mall madness, there were no reported serious injuries.
