dirty gindlesperger
Closely related to a dirty sanchez, this is when a man sticks a finger, his dong, or another similarly shaped organ into a woman's ass then draws a circle around her lip with the shit, causing her mouth to look like a fat mexican guy's belly button.
"So I heard you gave her a dirty sanchez last night!"
"No, I went all the way around and gave her a dirty gindlesperger."
