When you take a girl in the shower and you lather up her tits and then you knock her out with a crowbar. You give her a dirty sanchez and leave her out on the front lawn.
As I walked by my neighbors house I saw his girlfriend passed out on the lawn with a dirty sanchez and realized that her boyfriend had given her a dirty juanita.
When you forcibly make your family watch as you tear the clothes off your ex girlfriend and make her shove bottles full of TABS and laxatives then proceed to make your sister eat it.
Bro i think the cops are looking for me after doing a dirty Juanito
