brain slut

Someone who volunteers for research studies that mess with their brains (usually via psychoactive drugs) for some cash.

Danny signed up for 3 drug studies last week because he was broke, and went bat shit crazy...what a brain slut.

slut brain

When your Dominant puts you so deep into subspace that all you can think about is the unyielding, intense desire to be fucked.

I love when my man puts his hands on me. He gives me such slut brain whenever I am around him!

Slut-Brain

The ability to shut or block off the part of the psyche that is responsible for developing emotional intimacy and connection during sex, rendering intercourse a pointless pleasuring event with no real "magic".

You don't need to actually like someone to sleep with them, it's all about physical gratification when ya got slut-brain.
