The last phone booth got taken out a decade ago. We need a new metaphor for rapid, head to head inside fighting. Obviously, boxing in a cell phone doesn't work. Why don't we come up with something new? *boxing in a cubicle *boxing in a coffin *boxing in a submarine *boxing in a port-a-potty *boxing in a refrigerator box and so forth. Have fun with it.
Well since they will be dwindling away very shortly... How about 'Safe Space' ?? "Holy Cow Golovkin and Canelo are fighting in a Safe Space!!!"
Port a John makes the most sense. I've seen cubicles that are big enough to not be in punching range. Also, I feel like some boxing fans might not know what a cubicle is, as they don't work in offices.
