Ganja Greyhound 

A ganja greyhound is like a greyhound (vodka and grapefruit juice)but instead of using vodka, you dump the grapfruit juice into your bong and rip it to your hearts content.

Jon: "Hey man I'm mixing drinks, you wanna greyhound?"
Ed: "Nah man, I'm mixing drugs, lets have a ganja greyhound."

Greyhound 

A vehicle designed by Ford for the United States military in World War 2. It has had countless operators over the years and is even used by police departments in many countries including the United States. The most famous police role it actually played wasn’t in real life but in the movie die hard. The Greyhound was the RV (SWAT Van) that was sent in to assault Nakatomi Plaza. The vehicle is hit twice by Hans Gruber’s goons but before the criminals can destroy the vehicle John McClane throws C-4 into the AT crews floor and kills both of them.

The LAPD sent in the Greyhound once they saw the hostage situation was rapidly deteriorating

Greyhounding 

Any disgusting action done on mass transit - particularly airplanes - that ought to qualify individuals for the No Fly List and thus relegate them to Greyhound Buses for all future travel.

This can include masturbation, sex, public defecation, public shaving and more.

Vascular D was caught greyhounding by the person sitting next to him on the flight. He will never fly Wizz Air again.
