Wahoo Effect

Anything unexplainable happened that even complex solution tool set cannot solve.
Danny is now the most prolific stud in our team. He got some Wahoo effect in him. I was surprised that even the imperceptible, Junsky, was caught in his cobwebs of desire.

Droppler Effect

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.

The Tim Effect

When a supremely smart, intelligent, and competent individual underestimates their own proficiency and intelligence. The opposite of the Jenny Effect
It's so sad that Ivan is often a victim of the Tim Effect; if only he could see how intelligent he really is!
