A German Fire Drill: Four to Six people gather in a circle in a dark concrete room wearing sweaters woven out of each others pubic hair (or darkish gray spandex, depending on how much time they had) subsequent to each consuming a large portion of syrup of ipecac. The participants in the fire drill wait until the ipecac has its effects at which point they ferociously vomit on each other, creating a shower-like fountain of ipecac-scented vomit. The sound created by the people vomiting has been sometimes described as sounding like a german fire alarm, thus giving the practice it's name. Special attention is generally taken by participants to direct a majority of the vomit on the host's genitalia, as an act of courtesy and gratitude.
WE-OOH WE-OOH WE-OOH
What is that noise Sharon?
My son and his friends are having a German Fire Drill upstairs, sorry.
