When you have a "friend" sleeping in bed with you and you are "crossing borders" by having sex, feeling eachother up, etc. you on one side, your "friend" on the other. then you cross borders, that the girlfriend sets up, and "do it". usually tiedown free.
Danny and Jade wanted a little fun, but Jade didn't want him crossing borders.... He did anyway, now she's knocked up.

The act of having unprotected sex with one partner and then, without showering, having unprotected sex with a different partner, thus transferring the residue, juices, and secretions between the two parties either with or without their knowledge.
Gentleman 1: "Last night I had sex with Amber and this morning I had sex with Brittany. I didn't take a shower in between."
Gentleman 2: "It seems as though you've cross-pollinated...well done!"
