When a man initiates unprotected sexual intercourse with a sub-par class woman but - when he pulls out his penis - he is wearing a rubber (from the collection of old-dirty-discarded condoms in the woman's vagina). The phenomenon is like a battle between the penis and vagina, similar to a hockey fight, where the vagina "dirty jerseys" the penis with a condom and hence wins the fight.

Dirty Jersey is when you are fucking a girl in the ass from behind while she throws up into a trashcan.
This act is best performed with jersey girls who are well known for being trashy

To perform a dirty jersey you must have the mr. fantastic stretch power. You put you penis into a girls butt and stretch it through her intestines out of her mouth so she can give you a blowjob and be taking it in the butt all at once
