Massive brawls and food court fights broke out at more than a dozen malls across the US on Monday (local time).
The mall incidents, which ranged from minor fights to mass evacuations, occurred from Colorado to Tennessee, and Texas to New Jersey, CBS News reports.
Police are still unsure about why nearly a dozen brawls happened around the country, but say that social media may have played a role.
