How about this:
Hi-Speed is just as easy as driving a car! Un-matched impedances are the
holes in the signal integrity hi-way. You must go slower for bigger holes.
Instead of trying to explain in terms of bandwidth, try Flight Time and edge
rate. IE, if your signal changes state quicker and it takes the signal to
get from driver to receiver and back, the signal is Hi-Speed.
In car terms; the longer it takes us to get to work, the more we will be
interested in a good Hi-Speed Hiway.
Note; this rule doesn't care whether you have 100KHz or 100MHz signaling.
Hope this helps.

Subject: [SI-LIST] : Definition of Hi-Speed (UC)
Pardon me for asking this stupid question because I am at a loss of how
to explain hi-speed to my boss. He thinks that hi-speed is as simple and
straightforward as resistance = V/I and nothing else. Hi-speed should be
some circuits that need to operate at xxMHz or more. Anything less than
xxMhz is not hi-speed.
I would appreciate anyone of you experts out there who can enlighten me
in a simple and easy to understand definition so that my boss can
