Country star John Rich showed off a pair of Nike logos that had been removed from his soundman's socks.
Video of a pair of shoes being burned went viral.
The anti-Nike puns came next.
"Just Don't," posted one Instagram user.
"Just Blew It," posted another.
President Donald Trump has been persistently critical of NFL players protesting during the anthem, a movement Kaepernick started.
In an interview with Fox News last year, Trump told Sean Hannity he thought Kaepernick should have been suspended after his first protest.
"I watched Colin Kaepernick, and I thought it was terrible, and then it got bigger and bigger and started mushrooming, and frankly the NFL should have suspended him for one game, and he would have never done it again," Trump told Hannity, to cheers from a live audience watching the interview.
So far the President Trump has yet to weigh in on Nike's new campaign.
But the hashtag #NikeBoycott was trending on Twitter.
In pre-market trading yesterday, Nike stock was down nearly 2.3 percent.
ESPN reporter Darren Rovell, who broke the news yesterday, reported Nike's new "Just Do It" campaign would target 15- to 17-year-old teenagers and also include professional athletes Odell Beckham Jr., Shaquem Griffin, Lacey Baker, Serena Williams and LeBron James. Rovell tweeted Tuesday that the NFL did not respond to a request for comment on Nike's decision. In March, Nike and the NFL announced they had extended their longtime partnership for game apparel until 2028.
The irony of people discarding or defacing their (likely expensive) Nike merchandise to protest something they disagreed with was not lost on those who supported Kaepernick and his protests. Many poked fun at the newly declared boycott, even filming satirical videos of themselves "destroying" their own Nike gear in ludicrous ways. Others vowed to wear their Nike apparel more frequently or to go out and buy Nike sports gear to make up for the boycott attempt.
