Random Asian Running Syndrome - Asian kids on campus that are always SPRINTING to class, whether they are late or not, have RARS. Frequent strains of RARS cause a sudden stop in running, followed by a walk - What was it about that moment that they decided it was okay to walk instead? Why not jog? Overpacked backpacks are also a common symptom of RARS. Lunch boxes and non-weather appropriate dress have also been linked to RARS.
"Why is that Asian kid running with his backpack on?"
"He has RARS."
