Drugs are green, my bitches white and tonight I need fuckin' head

from Odd Future (Ft. Domo Genesis, Hodgy Beats & Tyler The Creator) – Rella Lyrics on Rap Genius

Meaning

Domo’s smoking some chronic, and tonight he’s fucking with a white bitch

He’s using the word “head” as a double entendre meaning “head” as oral copulation with his “white bitch” and also “head” like in “Head” Shop, referring to his “green drugs” (marijuana) and being an avid smoker.

He’s not referring to a “head” shop. Heads (or headies) are a certain quality (not to be confused with a ‘strain’) of weed. In order from worst to best quality it usually goes: Schwag (dirt weed), Mids (still some seeds usually left in the bag), Heads (usually pretty good weed that is near to, or on par with, medicinal-grade marijuana.)

The wordplay is still there though.
