Every girl I meet, always talking bout "I don't even wanna know Hopsin, ewe
Yeah, he got some skills but every time he put them eyes in it look like he popped some pills
I just wanna know Marcus, he's a sweet little innocent boy
from Hopsin – I'm Not Introducing You Lyrics on Rap Genius
Meaning
Marcus is nice while Hopsin doesn’t give a fuck, they just wanna hang with Marcus and not Hopsin.

The part with the eyes is explained by just the picture above
This.
(And YES we know Hopsin and Marcus is the same person, he’s just a two faced niggah.)
