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.

The way and extent that cultures influence each other. Gained some notoriety on the internet when used by Garnt on episode 23 of the Trash Taste podcast. Note that he didn't invent the term.
There has been some cultural cross-pollination between Japanese anime and western cartoons when it comes to visual styles.
