dirty smoothie 

When the man puts a fruit smoothie inside his penis, then ejaculates the smoothie into the woman's mouth.

Ann: Hey, I heard Mike gave you his special dirty smoothie.
Haley: Yeah. He made me a raspberry-banana one.
Ann: Nice.

dirty blueberry smoothie 

Another variation on the blueberry smoothie. After creating the blueberry smoothie, the person who is to eat the smoothie out of the host pussy sticks his/her finger up the girl's ass and plays with her poopshoot while eating her out. When finished consuming the blueberry smoothie, the finger is pulled out of her asshole and licked clean by the consumer of the smoothie.
This should not be confused with a chocolate blueberry smoothie, in which the smoothie is made in the ass instead of pussy.

"Wow, this bitch I picked up at a bar last night was a total freak... she loved me playing with her asshole, so I decided to make a dirty blueberry smoothie. I love dessert!"
