Roast Beef Theives or Roast Beef Theiving

The process of stealing Arby's (hinting roast beef) food by running through the Drive-Thru. When your friend is at the window about to get his food you run up and steal it and run away. This causes a commotion and you get double the food. Original Roast Beef Theives are located somewhere in the South End of Louisville where this process began.

Roast Beef Thieving is the act of stealing Roast Beef from Arby's. A friend will park to far away from the window at the drive-thru and as the lady/man leans out the window to give them the food another friend runs from behind the car and swipes the food. As he runs and jumps into a third friends car the first friend complains that an unknown man just stole his food. That man recieves his food and you re-group with those who stole the food and that's what we call the double.
"So we were all hanging out late last night and got hungry but only had six dollars between us. So we pulled the R. B. T."
