I'll Put it your ass, like i put in your mum
This is when someone is telling you they're gonna give you a rough time, and they’re not kidding. The mum part is just there to remind you that your mom might be involved in this mess.
I'll put it your ass like I put in your mum, and I'll make your mom watch.
You talked bad about me, so I'll put it your ass like I put in your mum.
You're gonna regret this, I'll put it your ass like I put in your mum.
