"A euphemism for, you know, less than well wishes for the president of the United States and it has become a kind of a radical conservative rallying cry," Oklahoma pastor Jeremy Coleman said of the video showing people within the nondenominational Cornerstone Church in San Antonio chanting the phrase. 

"It was gut-wrenching and heartbreaking," Coleman added, according to News4SA.
WHERE DID LET'S GO BRANDON COME FROM?

The video of the people chanting has more than 2 million views on Twitter. Church officials said the chant did not occur during services. 

"This past week, Cornerstone Church facilities were used by an outside organization. Cornerstone Church is not associated with this organization and does not endorse their views," the church said in a statement to News4SA.
