Silent But Deadly! unfortunately an all too familiar odor eminating mysteriously around groups of people, survivable outdoors, but toxic in an enclosed space, in which everyone looks around trying to figure out who let rip (even the smirking perpetrator).
sitting in the back of a pick-up truck with a group of friends on our way to lollapalozza, when suddenly the driver's side window rolls quickly down and the driver sticks his head out the window screaming "S.B.D.!S.B.D.!" dousing the front cab with ozone, while the guy riding shotgun is laughing his guilty arse off. if especially deadly, DO NOT be stuck downwind, i.e. in this case, riding in the back of an open truck slowly, or worse, trapped in the car itself.

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.
