Mentapheremones
The concept that individuals gain knowledge about a sexual partner's intelligence through the way they smell, specifically through pheromones that trigger the olfactory system and elicit an attraction towards their intellectual capacities. It suggests a connection between the immune system's response to pheromones and the perception of attractive intelligence, forming a deep bond akin to soul-mates or twin flames. It implies the idea of a profound connection on both a physical and intellectual level, potentially influenced by past lives or a shared history of the brain and soul.
The intellectual attraction between them was tanglible but it wasn’t until she smelled him that she realized there was an undeniable pull between them, as if their mentapheremones were in perfect harmony, attracting their sexy minds to one another.
