It's Metaphorical!

Taserface is a relatively minor villain in Guardians of the Galaxy: Vol. 2, but he leads the Ravagers’ rebellion against Yondu, and is responsible for the deaths of any Ravagers who are still loyal to the former captain. We actually understand what pushes him toward mutiny, but that isn't the point here.
Rather, the point is made by Rocket Raccoon. Taserface reveals his name for the first time in what’s supposed to be an awesome and fear-inspiring scene. But it doesn't go as planned, because his name makes Rocket laugh.
The raccoon takes his name literally, as if the new captain can shoot electricity out of his face. And then the funniest exchange of the movie ensues. His name is METAPHORICAL!
This becomes one of the movie’s running gags. In the end, when Taserface realizes that he won't make it out alive, he tells the Sovereign where Yondu is, and asks just one favor: that his nemesis is told exactly who revealed his location.
The Sovereign laughs in response, of course.
