The Dallas chapter of the League of United Latin American Citizens organized a lighthearted response Sunday to a woman dubbed "Taco Truck Tammy" after she was caught on a cellphone video threatening to call Immigration and Customs Enforcement officials on several Latina food vendors parked outside her Dallas home April 4, WFAA reported.

The 49-second clip has been viewed more than 160,000 times on YouTube since the video, featuring a woman identified only as Valerie, went viral.

Valerie later said she regretted her words.

"It was just a moment of a very bad choice of words," she told KXAS. "I regret the comment at the end. It was a flippant comment. It doesn't really reflect who I am. It reflects my frustration."

Sunday, several dozen neighbors met in the parking lot of a school, listened to mariachi music and munched on tacos, WFAA reported.

Carol Bell-Walton said the protest was a good-natured reaction.

"It’s embarrassing that it happened in the neighborhood," Bell-Walton told the television station. "When I saw that they were going to be out – I just wanted to come out and lend my support.”
