Dirty gramz
When you're in it for yourself and get your girlfriend/wife/partner to bend over(usually somewhere unusual eg. bus station toilets, weather spoons smoking area, court ushers office) and get her to the point of climaxing when you pull out and finish your self off to images in your mind from a old FHM magazine from the 90's. (While leaning back against your partners still bent body to keep her thinking you will be returning can be added for that Extra "fck you or ""dirty gramz""
I was pissed at my wife for checking out the waitor so I pulled a dirty gramz on her to make her relise I'm the one in charge,I'm the man...I was debating wether to allow her a "quick parking"(see separate definition) but decided it should be my day,my dirty gramz of a day.
