Wikipedia definition of (sexual) kink, from https://en.wikipedia.org/wiki/Kink_(sexual):
In human sexuality, kinkiness is the use of unconventional sexual practices, concepts or fantasies. The term derives from the idea of a "bend" (cf. a "kink") in one's sexual behaviour, to contrast such behaviour with "straight" or "vanilla" sexual mores and proclivities. It is thus a colloquial term for non-normative sexual behaviour.
The leather/fetish/BDSM/kink community is composed of folk who approach and incorporate personal kinks into our lives and relationships. We acknowledge our heart's desires and unleash our spirit to explore and celebrate. For some, “leather” is a specific subset of the broader leather/fetish/kink community in which personal protocols incorporating respect and honor are common and wearing leather is appropriate.

Dominant/submissive ("D/s") – a power
Of note: Submissives can choose to whom to offer their submission. They do not have to be submissive to all Doms
· Daddy/boy (&"boi") -- a D/s relationship where often the boy has some input
· pup/Handler – generally a playful relationship
· Master/slave -- a control/obedience relationship where the slave strives to conform to the Master's will
· Polyamorous ("poly") -- multi-member families
· The Nine Degrees Of Submission can help discern between nuances of submission
