Cross pollination occurs when, during a threesome with one male and two females, the male has anal sex with one girl and then puts his penis in the other girls mouth. He then puts his penis in that girls ass and then into the other girls mouth.
John is having a threesome with Jane and Crystal. He puts his penis in Crystal's ass then into Jane's mouth. He then puts his penis in Jane's ass and then into Crystal's mouth thus causing cross pollination between Jane's ass and Crystal's mouth and Crystal's ass and Jane's mouth.
When you introduce a friend from one group to a friend from another group, and they become autonomous friends, no longing requiring your services to hang out. Not necessarily a bad thing, but can be disastrous if left unchecked.
Dude 1: Dude, did you hear that Joe was hanging with Jane now?
Dude 2: Yeah dude. I introduced them a week ago and they don't even call me to chill anymore. Serious cross-pollination.
Figure A and B are brother and sister, or related in some way. Figure A dates or hooks up with Figure C while Figure B goes out or hooks up with figure D. Some time later, Figure C and Figure D hook up as well. This mixing of juices is called Cross Pollination, and is generally looked down upon in a modern day society.
Dude, they totally cross pollinated... cross Pollination is gross... I just really threw up a little in that cup.
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.
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"
