Immodium Challenge 

A situation in which without taking Immodium, you will almost certainly shit yourself. Examples include situations of fear, embarrassment or extreme laughter in which you lose control over your bowels.

Man, I wish I popped an immodium because I diarrhea'd all over myself and the audience while walking the tightrope. That was true immodium challenge.
