I found you laying down with Samson and his full head of hair
Samson was a Biblical Judge (military leaders of Israel), whose hair granted him superhuman strength. His lover, Delilah, betrayed him, and had his hair cut (after he revealed his secret), leading to Samson being captured and blinded
While the language implies the black queen has slept with the white man, that would not be the historical case. Cleopatra was from the Ptolemaic dynasty (thus Hellenistic — white) and Samson was an Israelite (thus Semitic — closely resembling modern Arabs in physical appearance)
Nonetheless, Frank is likely implying Cleopatra has betrayed her race — tying in with the “white man corrupts black queen” motif throughout the song
You could also view Samson’s “full head of hair” as an implication that the narrator feels inferior compared to him, considering his hair granted him superhuman strength. This would also fit in with the impotence of the unemployed narrator towards the end of the song.
