Gandalf Complex 

A psycological disorder, similar to Schizophrenia or Tourette syndrome, in which one believes they are the fantasy character Gandalf. This person may do things like appear in your home with thirteen dwarves, or can be heard whispering under his/her breath such things as, "Run, you fools."
There are two basic stages of this complex, the primary stage, 'Grey,' and the secondary, 'White.'

"I knew my husband had a Grey Gandalf Complex when he brought the Fellowship into our vacation home, referring to Point Pleasant as 'Middle Earth.'"

Little known slang term for toilet paper usually of the softer variety. Comes from the fact that Gandalf from Lord of the Rings has a long white fluffy beard.

Gandalf's Hair Dye 

When an old man with a very long grey beard braids his beard into braids and proceeds to shove the braided beard into a woman's asshole, leaves it in there for a few hours, and pulls it out, leaving his beard brown rather than grey.

Gandalf: my grey beard makes me look old
Frodo: go Gandalf's hair dye it
Gandalf: thankyou Frodo, can you help me unbraid it when I'm finished
