chained_bear Yeah, I think that's the connotation that most people mean when they use this phrase--a fleeting event, rather than an ineffectual one. But I guess those meanings kind of intersect in this saying. Oct 21, 2007
oroboros Interestingly, to me, is that an actual flash in the pan, when it catches the sun just right, is a good metaphor for a fleeting event. An inconvenient, incommensurate feature of the metaphor is that it's hardly of no effect when it blinds you momentarily! Oct 20, 2007
chained_bear The origin of this phrase is similar to that of "going off half-cocked." On black-powder muskets, a flash in the pan occurs when the flint strikes the hammer and creates a spark that ignites the powder in the pan (outside the barrel), but the flame does not transfer into the barrel. The powder in the barrel doesn't ignite, and the bullet (if there is one) doesn't go anywhere. So it's just a flash--no shot, no effect. Oct 20, 2007
