Not only is it a smoothie from persia, but it is aslo known as when two people with male genitalia go to a grave yard and dig up a 90 grandmother named Betsy. They will then each stick there left testicles in her vagina and there rights in her asshole. They will then proceed to batter her with baseball bats in the stomach, allowing fluids to come out of her privates and butthole. I personally have tried it and would definitely recommend, the 80 dollar testicuzi is nothing compared to this practice.
Banana smoothie is a phrase used to friends meaning "Please give me some attention".
The phrase is mostly used in the Australian language and mostly used as teenagers.
When someone shits in your mouth and you swallow it, and it's so gross that you throw up all over their asshole, then you lick the vomit off their asshole.
