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.
An annual fishing trip for men only. Beer, Poker and cooking of meat on an open fire far outweight the actual fishing part of the trip. Sleep is limited to short naps between meals, and during such moments of rest the other fishermen can make loud rude comments to disturb your bliss.
Dude I can't wait for this years Boonedoggle, no wife, no boss, just good food and free time.
Theme song sung during the trip is
I'm going fishin on the Boonedoggle, BoondoggleBoondoggle (sing like Cat Stevens Moonshadow) .. then add appropriate verses that make fun of the other guys.. very relaxing.
