look up any word, like crust punk:
 
1.
A curry, usually of dubious quality, eaten in the early hours of the morning, in a backstreet emporium after a long hard night of massive alcohol consumption. Named for Curtis Davies, a sportsman who has been spotted around Birmingham enjoying this kind of meal.
Hey Edward, you going for a dirty curtis later?

2.
similar to a Dirty Sanchez - when you get a finger or two covered in yeast infection juice and smear it across someones upper lip

The reference of Curtis is to Jaime Lee Curtis, most recently known from the Activia yogurt commercials. As yogurt is known to help reduce yeast infections in women.
Damn yo, that chick just got a dirty curtis!
