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.

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

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.
