The definition of "mircogoon" or "microgooning" is an action. Microgooning is a form of gooning/playing with your penis that involves using your index finger and middle finger as chopsticks around the base of your penis and "flicking" it at mock speeds.
Microgooning can also be used as a celebration. For example when getting a kill in a online video game to celebrate you can hit a quick mircogoon. The better the clip the faster the flick.

That's a clip *starts microfapping*
Im microgooning
Extremely tiny thong with just enough material to conceal the pussy. The open variety does not hide pussy, but may have a jewel, pearl or feather hanging seductively over the clit region. Hundreds of different styles by Lola Luna and other manufacturers are available. One daring version consists of a string of pearls which lies between the pussy's inner lips. Its only possible purpose is to stimulate the clitoris when walking or dancing.
In striking gold and green, this open embroidered microthong has a diamante drop front with green sequins and an edging of gold French lace.
A tinypatch of material which barely conceals pussy worn provocatively tied low around the hips.
The audience was restless, hungry, panting. Backstage, Yulia squatted in front of the mirror and made a final adjustment to her tiny microthong. The slightest misalignment would be disastrous.
