gyaru v
An upside-down V gesture.
The original term is called "Gyaru-peace", which is a combination of the Japanese pronunciation of "Gal," an English slang for women and girls, and the English word "Peace," which means finger gesture V.
Originating from Japan's Gyaru culture, it is a hand gesture that first extends the arm forward and turns the palm up and down after making a V-shape by hand.
