Crazy In Love Lyrics Meaning

it's about his mother

''Let me go crazy, crazy on you'',
''You just make me get so crazy
I go schizo, I get so insane, I just go schizophrenic'' - his mother was mentally ill

''They say that every man grows up to marry his own mother
Which would explain why you're such a motherfuckin' bitch'' - maybe there are no metaphors here

''You're only 24, but you're plenty more ma-ture
Than those other little hoes who just act like little girls'' - his mother was much worse as mother than average mother (it's sarcasm)

''You are the Kim to my Marshall, you're the Slim to my Shady
The Dre to my Eminem, the Alaina to my Hailie'' - he explains how much he loves his mother (it's sarcasm, he hates her, all this love and sex it's just masochistic sarcasm)
