Was bored/listening to Eminem and decided to give it a shot. Lemme know what you think.

I do DMT and LSD I got the whole alphabet inside me
Don't give a fuck about my health, I roll around in poison ivy
You tell me I won't do shit? Motherfucker try me.
Got your mom tied up naked while the bitch screams "Frets untie me!"
But you know I'm just teasing, yea I'm just tauntin'
This aint even me speaking, it's the fucking Oxycontin
I am not a rapper, I'm a guy just trying to be Eminem
And I'm not calling him out not trying to say I'm better than,
him, but what the fuck does better mean?
Stare you dead in the eye while I ingest the fucking ketamine
Sit back in my chair and think "man this is gon' be fun"
Then the chair tips over and I smash the one-fifty-one
But like I said earlier motherfucker I aint tryin' to taunt you
I'm immortal, until I kill myself then I get my ghost to haunt you
When I rap people shut the fuck up, they listen and just nod
Throw out your bibles, you aint Christian no more, bow down to your new God.

Pretty good
