Why is someone who's indecisive "waffling?"

Picture a waffle. Lots of little squares that are ideal
for holding syrup, right? So, what do you conclude
about the relationship between this breakfast food's
shape and being indecisive?

Nothing, I hope, because there isn't any relationship.
The relationship is between waffle and the Old English
word, "wafian," which meant "to wave." From that word
in the 16th century came another, "whiffle," which
described the wind when it changed direction. (Perhaps
someone had a lisp and said what sounded like "the wind
is whiffling.") Now jump to the 1950s and 60s and
whiffle ball, a game in which you hit a wind-blown
plastic ball with holes in it. That ball, like
indecisive people, could go in any direction.

So, why don't we say that indecisive people whiffle,
instead of waffle? Maybe someone talked with his or her
mouth full. I'm not sure, can't decide. Pass the syrup,
please.
