what does "fuck you'meds"mean? does "med"mean "crazy?"
When she heard Strike ascending the stair nearly an hour later, apparently talking on his mobile and in good spirits, Robin experienced a sharp stab of panic to the stomach as though she were about to sit an exam. When he pushed open the glass door, and she saw that he was not holding a mobile at all, but rapping under his breath, she felt even worse.
“Fuck yo’ meds and fuck Johari,” muttered Strike, who was holding a boxed electric fan in his arms. “Afternoon.”
“Hello.”
“Thought we could use this. It’s stuffy in here.”
“Yes, that would be good.”

Answer

“Fuck yo’ meds and fuck Johari,” muttered Strike.

Strike is quoting Deeby Macc, a rapper.  I think the line should be "fuck your meds and fuck Johari".  Meds are medications.  Johari is a Johari Window, a psychological tool used to help people understand how others see them.

Deeby Macc had therapy for mental illness while in prison.  My guess is that in the song, Deeby Macc is saying "take the psychiatric medicines and psychological bullshit you've been feeding me and stuff it somewhere rude".
