This is a song about "Marine biology"

As the chain swinglettin' shine, no sheenjust my dream

But what he doesn't know is that i'm sharp as a marine

Nigga, i'm a fucking, marine engineer,

Don't give a shit so my dick fuck bladders in your ear

In the "city of lights", it's hard to see clear

Nigga, i'm a fucking, marine engineer,

I'm like psychotic marine on laced lsd

Lock my heart up, this is jail, throw away the key

Made logically because he came outta school failing english, maths and biology

That's gon' make it hard to smile in the futurebut through whatever you see

This batmobile is real hard to steer

Nigga, i'm a fucking, marine engineer,
