When a man is having sex with two or more women and pulls directly out of one and penetrates the other without rinsing his penis or condom. Seen in many porn flicks.
Wow! That orgy scene had massive amounts of cross cuntamination going on! I bet everyone's genitals rotted out after filming!

The souring of a social situation due to a specific combination of women.
The party had a serious case of cross-cuntamination when the girl who slept with the hostesses husband showed up.
