What do the cool young guys say?

[Uniquely]

I've got a patient who can no longer speak due to traumatic brain injury. I am designing a talk board for him. It's a board with pictures on it, and when he presses that button, it will say whatever message you record into it. When we loaned him another resident's board to see if he could use it... she had a button that said "kiss my fanny" and he really loved that button, but that's not very manly.

This is a man in his early 30's, african american, had a physical construction type job, likes rap and hip hop. What do the young guys say these days to rib each other? Nothing profane or sexual, as his family is religious, and would not approve. Just something kind of current that isn't too foul. I'm kind of stumped.
