Jizz 'N' Run 

When you are doing a girl in the pussy and you are about to jizz, you jizz then get the hell out of there and she will never know what hit her.

Dude, I was totally doing this hot ass blonde last night. She had the tightest pussy and said she didn't want to get pregnant and I didn't want any trouble so i pulled a Jizz 'N' Run!

Run and Jizz 

The act of doing a full out sprint into a crowd of people while you masturbate onto poor defenseless people.

I saw my brother run and jizz at the football meet yesterday.

Jizzrun 

After the physical act of copulation, if the male ejaculate is allowed to spill inside the female cervix, she will most likely run or walk (at a brisk pace) to the lavatory to allow said ejaculate to drain from her nethers.

Last night my missus went for a Jizzrun but didn't make it, so I made her clean the floor...

With her undies.
