When you are getting a blowjob and the girl/guy sticks a pinky in your ass.
That Bitch gave me Pinky Wave.

Waving only the pinky at another driver that has pissed you off, thus insinuating that his penis is the size of your pinky. Also good for greasy-looking kids who have their music on too loud.
I gave him a pinky wave to go with his fake-ass spoiler and blown-out speakers.

Waving your pinky at a driver you see whom you would like to pull over to have sex with. If they wave back, go find a nice spot and do your thing.
That driver is so fine! I'll flash her the pinky wave, and hope I get lucky!
