sub drop
What does sub drop mean?
Sub drop is the comedown after the high. Once subspace and the endorphin rush fade, a submissive can be left depressed, weirdly exhausted, weepy, or just flat — sometimes hours or even days later. It's the body and brain settling after a chemical spike, not a sign anything went wrong. Solid aftercare softens it or heads it off entirely. The mirror version exists for dominants too — 'top drop' or 'dom drop.'
Origin
BDSM community term describing the post-scene emotional and physiological crash, paired conceptually with subspace and aftercare.
