After scoring goals in recent MLS matches, the French striker has rested up against the post with one hand on his hip whilst having his legs crossed.
The move, which has been labelled as 'Henrying', has attracted plenty of attention on social media with a number of Twitter pictures showing the former Arsenal star performing his celebration on Manchester United's Robin van Persie, boxing great Muhammad Ali and pop star Miley Cyrus.
Henry admitted he never intended for it to become a noted celebration but was happy to see it catching on.
"The guys showed me some of the pictures. It's kind of funny," Henry said. "There is nothing behind the celebration.
"I just needed a rest. I stopped there, saw the post in Houston, twice, saw the post the other day (vs. Toronto FC). Now everyone is doing stuff on the internet with it."
Henry's Red Bulls teammate Tim Cahill added: "It's fantastic. With social media, networking with the fans all around the world. (Henry) is one of the world's renowned athletes. Anything he does is definitely going to be an impact."
Below are some of the photoshopped images on Twitter of Henry performing his celebration.
