Can't wait for the exit hole
Give me room the entry wound
In reference to the previous line, this is a continuation of the “hollowpoint bullet” wordplay. The importance of life is beginning to fade for Lupe, and he feels the pain of the bullet on the inside (a hollow point is designed to explode when it hits its target causing a larger hole, and more tissue damage).
Lupe is awaiting the exit wound so that his painful situation will end.
