It's just the way Deadpool would want to be celebrated, with a huge and athletic flash mob. This video was posted to the Facebook page for DMX who contributes a song to the soundtrack with the expressive title of X GON' GIVE IT TO YA.
We think that title comes with at least 5 exclamation marks, but they're invisible to the naked eye.
(the music contains some bad language, just so you know. The film does too)
