Your Definition
A non-sexual emotional state of overwhelming softness and neediness- usually triggered by love, kindness, or affection-that makes you crave cuddles, head pats, warm hugs, or just being held like baby. People in serotonin heat often act extra clingy, whiny, or vulnerable in a cute-pathetic way. It's like being "in heat," but instead of horny, you're desperate for emotional warmth and baby treatment.
