Top definition
the act of disappearing from a social event or establishment without telling any member of your party why or where you are going due to being inebriated and in desperate need of greasy food. The person performing the Boonedini often walks home from the previous destination and makes at least one stop at a fast food restaurant/chip truck/greasy spoon to consume said food.
We were having so much fun last night on the party bus but after the last stop, I think Ryan pulled a Boonedini.

Hey man, have you seen Brandon lately? Oh crap, I bet he pulled a Boonedini.
