They call me a freak because
I like to spit on these pussies 'fore I eat them

from Eminem (Ft. Lil Wayne) – No Love Lyrics on Rap Genius

An example of taking something literal and turning it into something notably metaphorical:

Eminem is considered a “freak” (someone who does a lot of kinky shit during sex) because… he likes to “spit on” (rap about) these “pussies” (weaklings in the rap game) ‘fore he “eats them” (dominate them).

Notice the pussy-eating pun in honor of Lil Wayne, the Great Pussy-Eater of All Rap (so it might be another subliminal shot at Wayne in this song, as suggests the conspiracy theorists)

(If you want the literal meaning, I’m sure there are a bunch of porn sites who can help you understand.)

spitting on someone in rap is showing them disrespect “hence the name of the song No Love and also the video was about bullying which I’m sure Em used as a metaphor for this song.

Possibly dissing Wayne here. Saying up above “Why the fuck would i join them when I beat them”. He answers that here, saying he gets on the song with Wayne just to make his verse look like shit
