Cross Pollinator 

When first one male with facial hair on his chin (a soul patch, aka pussy tickler, or goatee) performs oral sex on another male, receiving cum in his facial hair, then subsequently performs oral sex on a female, thereby transferring the first partner's cum into the second partner's vagina.

They totally had a threesome last night, and he played the role of cross pollinator. Ewwww.

Cultural cross-pollination 

Stargate SG1, S1 Ep14 "Hathor", October 24th 1997, the character Dr Daniel Jackson uses the term when referring to his canonical works from the Stargate Film when looking at Hathor's Egyptian Sarcophagus which was found in a Mayan Temple.

"... they recognised the significance of an Egyptian Sarcophagus found in a Mayan Temple. And since I was the only one to ever research cross-pollination of Ancient Cultures... they tracked me down"

Term is later popularised by Youtuber Gigguk during 2020 during a Trash Taste Podcast episode.

"And since I was the only one to ever research cross-pollination of Ancient Cultures... they tracked me down"

And alternative way of saying Cultural cross-pollination
