Flying the mile is getting high through the use of marijuana. In order to fly the mile you need plane tickets (Marijuana), and a Plane (device used to smoke). If your flying first class that means you have smoked nice bud. but if you are flying coach then you have only smoked regular bud. A Pilot (Pot Head) is frequent flyer.
Harry the pilot decided that he was going to fly the mile, but the authorities confiscated his plane, alot with his plane tickets. I am munchin' hard because i just flew the mile.
