Shaking a load (e.g. boxes, furniture) after tying it to a trailer, to assess if it is sufficiently secured. To pass the Graham Hall Test: when you shake the load, it should also shake the trailer. If not, then you haven't secured your load properly, and you should consider re-tying it.
That Lawnmower definitely passes the Graham Hall Test; When you shake the mower, the trailer shakes too!
Let's do the Graham Hall Test, to make sure my fridge won't fall off.
A modification of The Houdini; a guy has sex with a girl doggy style, and then half way through, stops and says he needs to use the bathroom or begins to finger her. A friend then sneaks in to switch places with the original guy. After a few minutes of this, the original guy then calls the girl and gets her to pick up while his friend is banging her, and talks to her. On the phone. Hence--- The Graham Bell, as in Alexander Graham Bell, inventor of the telephone.
Joe: Did you here what Steve did to Lisa last night?
Matt: No. What'd he do?
Joe: Oh it was awesome, he totally gave her The Graham Bell with Kyle.
Matt: Whoa! No way!
Joe: Yeah he talked to the bitch for 2 minutes before she realized she'd ben 'Graham'ed.
Matt: Lol Slutz
When you cum on someone's feet then give them a blow-job.
"On a road trip to Disneyland, we stopped for the night at a Super 8. As soon as I thought my buddy was asleep, I surprised him with The Graham James."
