Get the a Gandalf mug.
1. A wizard from J.R.R. Tolkien's magnificent legendarium.

2. A pipe (used for tobacco or marijuana, but usually marijuana) which is shaped like the pipe that Gandalf smokes out of in Peter Jackson's film adaptation of The Lord of the Rings.

This type of pipe has a normal, rounded bowl attached to a very long, thin stem.

When smoked, the bowl is held in front of the torso, somewhere between the nipples and the bellybutton, depending on the length of the stem. Longer stems are more desirable.
1. Gandalf is smoking some pipe-weed.

2. I am using a Gandalf to smoke some pipe-weed of my own.

Get the Gandalf mug.
1. Growing a long white beard, much like that of the Lord of the Rings character it was named for.
2. Hitting something with a big stick
3. In a sexual situation, pulling the old man switcheroo when the lights go out. You switch yourself with an old man and by the time your partner notices, you have slinked away into the night.
1. When I get old, I'm just gonna Gandalf that shit.
2. I Gandalf (ed) that dude's mailbox the other day.
3. We weren't really that compatible, so I just hit it and Gandalf (ed) that bitch.

Get the gandalf mug.
The term used when someone driving assumes it is okay to indicate or directly change lanes before looking in their mirrors.
This confident action was named after Gandalf from the Lord of the Ring films. Assuming that he or she is the superior on the road and that others on it "shall not pass", hence the name, Gandalfing.
It is usually subtly mentioned by a passenger when they notice the driver committing this.
"Gandalf" - said under your breath when you notice them do it.
Alternatively, "are you gandalfing?" or,
"did you just Gandalf?"
