The weary
jaded feeling of "letdown" that one usually experiences after a much-anticipated event (such as a
talent-concert or other much-hyped cultural bash, dinner-
date, "important" business meeting, etc.) which turns out to be significantly less satisfying or worthwhile than had been expected or hoped for. So, like the "Doppler Effect" that is heard as a noisy vehicle zooms by (the sound of the jalopy'
s engine is higher as it bears down on your position and then drops drastically in pitch as it rushes headlong into the distance), one's
mood and emotions suffer a similar "roller-coaster" or "
sugar-
crash" journey... you are all keyed up and excited beforehand with your heartbeat going a-mile-a-minute as you eagerly anticipate the looked-forward-to event, and then afterwards you feel disappointed and exhausted, with your whole being slowed into a state of draggy disillusionment.
