The sister of the dirty sanchez. During sex, when the male licks or kisses the butt of the female, then comes up to kiss her on the mouth. Usually not appreciated.
If I could give just one dirty lopez, it would be to jennifer lopez. Man, would that piss her off!

Laying on your back while recieving a BJ right before busting a nut, lift your legs up, lock your feet, and push your feet in. This forces the girls head down, making her deep throat. Then bust in the back of her throat. Don't let go until she swallows everything.
I was getting some head, and totally gave my girl a Dirty Lopez.
