Practice written vs Snake

Smooth and never ending, it's a river for my flow,

but I won't just look at rap and admit it's all I know.

I've seen the ins and outs of horror, I'm a killer on my own.

as I encircle snake and choke him, this is slither.io.

I can't stand all these animals, and I feel like Artemis,

ima hunt these beasts down until I only see carcasses.

And it's not that I'm bad, I just can't relate to them,

but if some people were gone, won't the world be safer then?

Lost in the haze, I be kickin' the dirt,

shot myself in the leg? No I just tripped on the curb.

My mind's foggy but I lock in, spittin' a verse.

Not a strongman but I feel like I'm liftin' a curse.

Generational wealth got me sitting by the backseat,

so these words became my life, and I live inside a rap beat.

You're all shit-faced, someone fit this guy a nappy.

What's an idiom? Y'all really kissing my asscheeks.
