Nerd

As a BDSM or kink role, nerd usually refers to someone who embraces a passion for intellectual or niche interests, often playfully showcasing intelligence or geeky enthusiasm.

This term may also describe individuals who integrate their intellectual passions, analytical skills, and niche interests into their kink practices. This might include fandom-based roleplay, nerding out on BDSM practices, safety, or education, or high-skill practices like rigging.
