Masturbation
Inspired by lyrics from the Teddy Hyde song Sex With a Ghost
Teddy Hyde : I’m getting jiggy with a rifle
One of the ugliest fruitiest male in the word
You a jiggy zar type boy.... boy bye
A combination of "getting jiggy with it" and "Gnarly". Used to describe a noun as something very cool and hip.
These pizza rolls are jiggy gnar gnar, I can't get enough!
