When someone throws fast food bags out the window of their car because it is filled with them and they are too lazy to find a trash can.
Dude 1: "Dude I found a whole bunch of fast food bags in the bushes outside my house..."
Dude 2: "Oh yeah, that was me... every time I come over I eat some Cajuns and dump the bag in those bushes."
Dude 1: "You lazy ass! Can't believe you would do a fast food bag dump off by my house!"

When you throw away fast food garbage already in your car, while you're actually going through the drive-thru of a fast food restaurant, in order to make room for fast food that you just ordered or received at ANOTHER fast food restaurant.

Often the immediate need derives from having to throw-away 32-oz. cups to make room in the cupholders for new carbonated beverages. But the need also derives secondarily from having to throw-away day-old (or week-old) bags of fast food on your passenger seat, floorboard, or backseat that are making your vehicle aromatic with the scent of remnants of quarter-pounders, supreme burritos, or buckets of chicken.
When I was going through the drive-thru of Taco Bell on Monday, I had to do the Fast Food Drive-Thru Dump-a-Do to get rid of my bags of McDonald's from Friday.

The next day on Tuesday at the Burger King drive-thru, I had to do the Fast Food Drive-Thru Dump-a-Do again to get rid of the Taco Bell garbage.

On Wednesday, I had to do the Fast Food Drive-Thru Dump-a-Do to get rid of my Burger King garbage to make room for my Wendy's #2 combo.

On Thursday, I had to do the Fast Food Drive-Thru Dump-a-Do and get rid of the Wendy's trash to make room for my KFC.

Friday I took off sick and ate Ramen noodles at home.
