Fuck you with an umbrella, then open it up while the shit's inside ya

from Eminem – Stay Wide Awake Lyrics on Rap Genius

Meaning

This is a possible reference to a quote from the movie The Last Boy Scout starring Bruce Willis that goes:

“If you even look at her funny,
I’m gonna stick an umbrella up your ass and open it”

Em has paraphrased a quote from the same movie in one of his older songs, which increases the likelihood that this reference was intentional.
