Definition A media coinage for bronchiolitis obliterans–BO that was linked by a plaintiff’s lawyers to the consumption of microwave popcorn which liberates diacetyl, a chemical used to produce the artificial butter flavouring.
Comment Several manufacturers of microwave popcorn settled pending lawsuits out of court. Not surprisingly, the data linking the putatively causative diacetyl and BO was flimsy, and the plaintiff’s experts largely scientasters. But most manufacturers know it’s cheaper to settle than go to trial even if they’re right.
